So who's running the Scoggin Dickey TPI crate motor with the advertised 357 HP?
I'm considering this motor as a replacement for my 305tpi and wanted to hear some comments first...

From what I can tell, I'll only need 350 injectors and the l98 computer...correct? I'm guessing the crate motor comes with a knock sensor.

Thanks,
S

Yea, I want to know what these motors come with that they advertise such high amounts of HP for a decent price. Do they give you their version of TPI on top of it, or is it 357 advertised HP with a stock TPI put on top (not likely) or with a modified TPI or what?

Say for example you get a ZZ4 crate motor. That is 355hp/405tq with a 650cfm carb and headers. Throw TPI on it, and surely it will restrict some of the HP and add a little more TQ. But what are they doing that they get 357 advertised HP out of it?

They use edelbrock runners on a tpi plenem. For sure its port matched. It just makes sense to port it. They also used 1-7/8 headers. As for throttle body I'm guessing 52mm. Wow those headers should make plug changes fun.

"This all new Vortec TPI engine will bring new life to your TPI equipped vehicle. The brand new engine assembly is supplied with a powerful hydraulic roller camshaft and our exclusive TPI Vortec baseplate. The proven combination produces 357 HP and 416 ft/lbs of torque. Requires the use of EGR kit SD3816, headers, and 350 injectors.

*Dyno tested with Edelbrock runners, 52 mm Throttle Body and 1 7/8 headers.

Compression is 9.6 to 1
THE CAM IS A HOTCAM.

I guess the cam is why.

not impressive if u ask me. the differences between this motor and the ZZ430 (hotcammed fastburn385) are the heads and induction type(carb). that's it. the zz430 is a fast burn 385 with a hotcam. that engine makes 430 hp. while this one only makes 350? the heads are not worth almost 100hp u think? maybe 30-40 at most? that same motor with carb or better fuel induction should make around 370-380? what do u guys think?

I would think if they mounted a Superram plenum and runner kit on that engine instead of the edelbrock runners, it would add another 30-40 HP easily.

adding another inductin setup on that crate engine will be defeating the purpose of that setup already onit. SDPC designed that engine for a reason. That engine is a nice replacement engine for those who already have TPI and dont have or want another induction setup. Why bother buying it if your gonna pull it apart and put a superra on it..... beside it has vortec heads so the superram wont fit right I have been eyeig this engine as well and alos wonder how much more HP can be found from using the fastburn heads instead.

e-man

The SuperRam uses the TPI base it will fit fine.

I agree, I am making 360 hp (306 @ rw) w/ZZ4 cam. see sig.

wyclefsirocz

my dad has the motor in his car and it makes 292rwhp@5100rpm
and a nice over 400lbs of tq from 3050-4750 peaking at about 439lbs of tq.
the car is a auto w/ turbo 400 and runs a 12.7 in the 1/4(2800 lb car) w/ 60's of 1.8. this motor is very streetable. do not get under drive pulleis with this motor. power steering wil be very tough if you do(don't know why but it is)

also the car is a 78 monza, shes got a decent gas milage with 3.55's. about 16highway/12 city. (its not a 700r4 tranny, mind you)

lots of tq. all most where its too much for that car. but in a 3rd gen it would be a great mototr imho.
i plan on getting one when my 305tpi goes.

I have this motor as well. actually i copied mine from an article before they even sold a crate motor. Its taking me 10 months to finish but i got my car back from a shop last week. My car has a lot of lope to it, my car needs a few things adjusted because i cant seem to run the ac at idle speeds without killing the car, plus its running about 230 degrees which is hot, but im getting there, did a nice smokey burn out just a little while ago, I upgraded from a 305TBI to this its nice

The Hot Cam'd Fast Burn 385 is rated at 430hp with a carburator. It's also $1000 more than the 360 TPI. A TPI set up on the Fast Burn will reduce the hp number some.

The 360 TPI does use a cam that matches the Hot Cam though.

While at the end of the day after extensive clearancing the Superram plenum and runners will fit. Although the SDPC base and SR plenum runners in their stock form will not even alow for a mock up where all the bolts are actually aligned properly.

This a very uncommon combo but it resides atop my 383 right now.

Apologies as this does not relate to the crate motor but I like to throw out this piece of info as most folks have no idea that there are alot of issues with the SDPC base and aftermarket runners, the SLP runners also need to be slightly clearanced to fit although nowhere near as extraeme as an SR setup.

This thread is from 2003, better put your flame suit on...

The Scoggin Dickey crates are very credible...

Id take a new GM crate anyday over someones "rebuilding".
Warranty, too.
Been down the road with high end rebuilds that dont last 100 mi, rebuilt heads that have guide issues etc no thanks. Try getting a shop even local to stand behind it LOL!!!

If it were for a drop in mild driver type engine Id buy a GM piece.

I agree. GM builds a great motor. Not always for everyone, but generally speaking, unless you're building an all out beast, you can't beat the quality and reliability, and they're not much more money once you figure in machine work for an old engine etc. etc.

I wanted TPI engine with at least 300 hp and I wanted stock look.

This Scoggin Dickeys crate is designed for TPI and it has power I want.
