I am building up my 350. I will be getting rid of the TPI system and going to a carb and intake.

My question is can I get 425 to 475 hp out of a 355 or will I have to go to a 383 stroker?

I am wanting to use Dart PRO 1's 200cc heads, a Team-G hi-rise intake, and a holley 750 DP for the top end.

Im not sure on the cam.

Does this sound like a good setup. It will be backed by a 700R4 with a 3000-3500 stall, 3.73 posi, and DOT tires.

I will be running the 1/8 mile.

I need some advice on my motor and would appreciate any help you guys can give me.

P.s. I know this has proably been asked thousands of times, but I have certain parts I would like to use and didnt find what I was looking for with a search.

thanks.

 

Well, if you are only running the 1/8, why get rid of the tpi? ;p

Well, I'm sure you can do it with the 355, but at a greater cost. Would probably be easier with the 383.

 

sounds similar to a 355 i built a few years ago. you won't have any problems making decent HP. if you've not built a lot of engines before i'd stick to the 355, a 383 can get to be a lot of problems making sure everything clears and doesn't crash into each other.

 

This won't help much, but there is a street legal 8 second 68 Camaro in MD runnin a 355.

 

Go 383, I built the one in my sig not too long ago.

 

sig please.

 

oops sorry. Here ya go.

 

How much horsepower you pushing?? I figured 500+ but wanted to know if you had any real numbers.

 

www.strokermotor.com

they have some good stuff that wont cost you a whole lot more than a fresh 355. IMO
Thats where I am getting mine from and they seem to be pretty good people...

 

I used desktop dyno and got about 600 HP and 530lb TQ. I dont know how accurate it is but Im still dealing with fuel and spark tuning now. When I get some numbers ill post them. Racing next fri.

 

Kinda on topic with the thread, why dont you see the 305 listed in stroker kits???

when it comes to the block, a 350 is just bored more. the 305 and 350 use the same crank.

heads and other crap can be moded.

so why dont you see the 305 listed under 355 or 383 kits???

cant someone just bore it to 350 or more, espically if it need boared already and then do a 355/383 kit???

or do you even need to bore it, would a 305 accept a 355/383 crank n rods and just use the stock pistons. sue it wont be as big but it should work.

just full of questions. seams odd how the 305 gets left out.

 

Well a 350 is not just a bored 305.
It you bore a 305 to a 4.00 bore you wouldn't have any cylinder left.
The 305 & 350 cranks have the same stroke, but that's it! The counter weights are in different locations.

A stroked out 305 by consensus is not cost effective.
A 350 crank in a 305 or visa versa would require a huge amount of balancing. (Not cost effective)

OK to answer a few questions.

jd13, I am getting rid of the tpi for different reasons. Cost, limited RPM, and basic simplicity.

ede, No I have not built many motors, especially a stroker motor. But I do have a few guys that build strickly race motors that will help me.

rocc4u, I will check them out. Thanks.

gtababboy, Looks like you have a good setup.



But the main question, Can I make 425-475 hp with the 355 using stock rods and crank. Of course new pistions.

thanks for all the help, If you guys have any Ideas of info let me know.

 

IMHO, I would do the 383...for 1/8 mile, you want TQ, and with a 383, you'll get more per cube that you would with a 355.

 

Of course you can make a 425-475 HP 355. Just go with the edelbrock setup that gives you 420 hp with a set of RPM heads. Then you can just do a little milling, get ahn Edelbrock performer RPM intake and a carb. This is the easiest way but not so much the best. It may also be the most cost efficient unless you just want to get nitrous.
Try to put a combo together for someone to desktop Dyno. Its not perfect but it will give you an idea. Definately rid of the TPI to save money and make everything so much easier without computer restrictions. That is my opinion only and that is what I did without any regrets.
The key is to match you heads, cam, intake, carb, stall converter and rear end but if the first three go good (heads, intake, cam) you'll do fine with HP.

 

IMHO, that's fine, but I would never use the Edelbrock RPM cam.....not for anything on the street. Waaaay better grinds out there now...

 

yeah, Im looking into a comp cam, push rods, guide plates, springs and roller rockers.

I want to build my heads my self. Get the bare 200cc Dart Pro 1's and add Manley race flo valves, and then add the comp parts.

Of course I will do a little port and polishing on the heads before I put them together.

Add this to a 355, flat top pistions, Team_G highrise, and a holley 750 DP.

Could anyone do a desktop dyno with these parts. Im not sure on which cam so just add a good one in.

I will be using a 3000-3500 stall, 3.73 gears, 700r4, and dot tires.

thanks.

 

doesn't eddlebrock or is it holley? that has the systemax II kit in summit racing? 425 bolt on hp, for about $1500.
doesn't sound like a bad plan to me.

 

That would be Holley...

I don't know, It's hard to look at a set of Edelbrock 18° heads, Victor Jr. & a Lunati Cam as being a waste ????????????
