I was looking at the hot cam set up?? I know it can make 430+ hp but I think i want alittle more and for sure more torque then you gain with the hot cam set up. Plus if im going to buy a set of cylinder heads I think I would rather get something better then the fast burns maybe afrs or edelbrock with an air gap intake???? anyway if anyone knows of a good proven hp + torque set up for the ZZ4 I would really love to know about it. again im looking for about 450-500 hp and about the same in torque if i can. I know stock my motor has 355hp and 405 torque. the motor is going in a 70 camaro with a 700r4 and 3.42 rear gears.

Check the Scoggin-Dickey website. They have a ZZ4 (I think it is in the custom section under crate motors) in the horsepower range that you want. As I recall, they are claiming 465 horsepower. Check the equipment combo that they used.

It is under the "Drag Race/Pro Street" Engines, p/n SDZZ465B. The price is $5700 (which does not include shipping).

well, thanks alot that motor they had has a 575 lift cam the hot cam was only 525lift hhhm the hot cam makes 430hp and like 413 torque hhhhhmmmmm wonder if its worth all that lift for the little hp gain????? wonder how it will idle??? 465hp and 430 torque does sound really nice thoughalmost perfect hhhmmmmm damn nice find though I wonder if it will gain any hp with diffrent heads??? I should look into this but then again the fast burns are kinda cheap lol thanks bro :lala:

Marshall89ws6

i think im makin something like 500-550 hp

Blackroc86

The Fastburns are kina cheap??? Where can you buy the "cheap"?

Can someone tell me how the zz4 is making 350 hp with L98 vette heads and an LS1 is supposedly making around 330 hp with far superior 200cc LS1 heads and a similiar sized camshaft and a higher compression ratio.

I just don't get it.

Because the ZZ4 s measured on a dyno stand with a carb, and the LS1 is measured in a chassis with exhaust, water pump, etc. etc. Even though it's crank HP, you lose a whole bunch of engine output when you stick a motor in a car and make it pass emissions.

and close to 400 with headers.

that's not playing fair. It's getting harder to beat the rich kids. I guess since I'm 30 I should stop trying. Or figure out how to get rich myself.

The LS1 is not measured on a chassis dyno, it is measured the same as the ZZ4. The LS1 rated power is not the peak power that the engine makes, it is quote lower in the lower band, for several reasons.

RB83L69

The LS1 spec (or the spec for any other production car motor) is given measured at the crank, but with the engine as installed in a chassis: all emissions devices installed and operating; computer controls as installed in the production version; a normal complement of accessories installed and operating such as an alternator, water pump, etc; the exhaust system and air induction as installed in that particular chassis (one reason why the otherwise identical L98 has different ratings in Camaro or Firebird); etc. The ZZ4 spec is given on a dyno stand, long-tube large-diameter headers, no water pump, no alternator, no emissions (it even says so in the catalog), near-ideal intake and air cleaner tract, etc. etc. Even though they're both crank numbers, they're a long way from apples-to-apples.

jcb999

with all attachments as would be needed for installation in a 3rd gen.

That sounds about reasonable... 350, taken down to 308 by the typical things that happen when you put it into a car... it's a normal situation. Think about when people talk about "my builder says it did 365 HP on the stand, why am I only going 14.7", after they put their stock TPI or their LG4 exhaust or their "drop-base" air cleaner with a 3" element and 2½" drop on it.

As I recall, the 308 horsepower was measured at the rear wheels.

We had a carbed one on a chassis dyno the other day. Put down in the neighborhood of 255 HP, but was running pretty rich. So I'd say close to 275 to the ground would be a reasonable expectation with headers and good exhaust like this car had.

Since i have no mechanical skills or engine building skills i just bought a bunch of "off the shelf" parts. I was going to go with carb and take out my tpi but i really did not want to do it. So after i bought the fastburn 385 i saved and after 7 months of saving i finally started buying aftermarket f.i. and other parts. Well, two jobs later i have "collected" a miniram for fastburn heads, tpis 52mm tb, new accel 24lb inj., msd 6al ign box, edelbrock jet hot coated headers, hot cam kit w/1.6 ratio rr, new water pump, underdrive pullies, and other parts for my swap. TPIS claims 352hp out of their fastburn set up and the cam they used was a bit smaller than the hot cam so my set up should be good for me! Once again, that is what i have been told by TPIS so we will have to see what it puts to the wheels, since that is what counts in the real world. I think with a little head work and a larger cam this set up has some potential but if i go to take the motor apart it is going to get stroked for more displacement. Thats way down the road. Need some suspension work first to use the "new found" power. I just got the motor in on saturday so it is not running yet. Hopefully by december as i find time it will be running strong. As for a chip, i am using a fast chip for now b/c i think it would be difficult as hell to try and burn my own just from my stock chip. As i get more equipment i plan on burning my own b/c you can always do things to get more power and basically a better running car than having someone 1000 miles away doing the "tuning"! From what i understand the ZZ4's internals are good for 500-550 hp stock, so watch what you put together. If you want some major power like that i would just buy the ZZ4 block or any block for that matter and build it up yourself to handle anything! Rather than buying the crate motor. Just another idea if you have a way of doing that. Good luck

I have to say I beat 2 diffrent LS1 cars one was an auto that had a lid air cleaner exhaust cut out and better trac +++ then me and I got him by 1 1/2 cars the other LS1 I raced was a 6 speed ws6 who knows what he had I smoked him pretty bad atleast4 or 5 cars not even a good race. I did this with the stock ZZ4 motor making 355hp and 405 ft torque. I guess my 70' camaro must be lighter or something but I was told other wise anyway I have 3.42 rear gears and a 700r4 tranny msd ignition and 2 1/4 flowmaster system. Oh to answer some other people I emailed 2 diff places and asked someone at the local gm performance shop the ZZ4 motor is measured on a stand threw headers and mufflers it also had the performance water pump on it that it comes with and there intake also comes on the motor.
I think after all the stuff I have looked at on this motor I am not sure if its worth going with much more then the fastburn heads with 10/10 gaskets air gap intake with a 750 dp and a 234/242 575/595 cam I am told it wont get much better #'s 470 hp and 435 torque instead of 430/430 that the hot cam makes but it will get me in the rpm range I want 6500 max before hp drop. I was kinda lookin for more power then that but if I am beating these guys now who will I race if I gain more then 100hp lmao LS1 with NOS. Oh ya I got that too I will hook up with a 150 shoot if I ever need it and im sure I will cause there are some pretty naste mid 11 LS1's in town . I would still love to see any other combos anyone can come up with cause as I see alot of peaple are looking at this post so im sure they wanna know too
Thanks again everyone

Hey, i was kinda tired last night while reading your post! So it is going into a 70 camaro and you are going with a carb. Sorry for my post! But it is a "proven" combo from what i have been told by others too so we'll have to see. Yeah, i'm surprised with your races. I have heard of thirdgens only running 13's, low 14's with ONLY the ZZ4 installed. You do have a higher gear though , whats your stall? You could be hooking a lot better too though, i don't know! LS1 with the right drivers should be low 13's, high 12 sec cars stock! Well, good luck with whatever you do.
