Hey guys. I finally picked up an 88 350 long block to start my engine build. I wanted to run my idea past you guys to see what you think.

Here is the build.

350 block out of an 88 Firebird

This Voodoo Cam

These World Sportsman II Heads

I am going with 1.52 Comp Cams Magnum roller rockers, and the appropriate Lunati Springs to support the Cam lift.

I plan on re-using the crank and rods from the motor, getting flat-top or dished pistons to keep the compressions right around 9.1 or 9.3-1 and going with a TCI stall converter. The dyno at the machine shop said I should be running right around 300-320Hp and 400ft-lbs of torque at the flywheel.

I am keeping all the accessories from my 305 including my Q-jet carb, AC etc.

So what do you think? Decent or too much?

 

first that particular cam is for an LS1

you might like some thing bigger than that anyway and more compression unless you plan on driving it every day

 

do it right stock rods and crank are weak, go for this poor boy special at least... http://www.strokermotor.com/RA383.htm

 

I'm not stroking the motor. This car is my daily driver so I'm going to keep it as a 350 or if the cylinders need to be bored, I'll go .030 or .040 if I must. I've got to be able to run 87 octane in it. That's the kicker. As a daily driver, $3.25 per gallon is killing me as it is. I couldnt imagine paying $3.50 or more for the premium just to start the damn thing. hehe I'll have to see if I can find a Voodoo in those specs for an 88-89 motor.

 

stock rods an crank that are inspec. will handle all the HP that engine is going to put out at this point besides that is $1000 of extras that you dont need to make a 350 fast... plus machining on top of that....

 

BINGO! Stock crank and rods should be good to 400 hp easy. Just upgrade the rod bolts. Thats truly one of the weakest links in the rotating assembly.

 

yeah well i wont argue with people over motor building just giving a sugestion, IMO using stock parts is just limiting yourself. specially when u can buy new better parts for a little bit more then having your stock stuff inspected and machined....id rather have a 350 thats making plenty of power that i dont have to worry about being a time bomb then having a motor running stock internals making power running on the ragged edge...you want a good reliable motor build it right with good parts and about 9:1 compression and have power and reliability.....

 

Did you ever see the car craft where they took a 2 bolt 350 from a junk yard rolled in new crank and rod bearings. And then progressively added no2 un till it popped? It didnt blow untill It reached 599hp and 655tq And when it did blow it was cracked the ring lands.

 

didnt see it but have heard of it, all well and good not saying that the sbc cant take some hellacious abuse, but lets not be ignorant about it, how long do you think that motor would last constantly on 500hp or maybe even 400....it could make it or it might blow, its a coin toss.....im saying for a lil bit more money he could build a qulity stout motor, but its a moot point cause for the 300 hp he wants stock stuff will be fine, but most people will want more after a while...

 

Is it possible to use a cam made for 1997 - 2002 in a 1988 block? I had a non-LS1 350 from a 96 Silverado that I wanted to put this cam in originally. However that block is now 1000 miles away in a storage facility. I didn't have enough room to bring it with me when I moved. I found an 88 Roller block and figured it would work. I thought Cams were pretty swappable overall?

 

as long as the cam is a gen 1 or even gen2 (lt1) roller cam u can use it....

 

LOL I've got a 67 Camaro sitting in a garage at my Parents place that needs a Frame-Off. When I get settled in a place where I have my own garage and can once again use my tools...I plan on going a little insane with it. Say...Twin Turbo LS7? hehehe You can click the link in my sig to see the car as it is now. Hasn't been driving since 2000...

 

nice 67, i had a 68 till about 3 months ago and i got rid of it to get some cash for my third gen....

 

Well....damn. Lunati doesn't make a voodoo roller cam for anything earlier than 1997. How do I know the cam is specifically for an LS1? LS1's weren't the only 5.7L motors used in 1997...

 

try lun 60120lk, 60121lk, 60122lk,60123lk cams thats the roller voodoo cams.... http://store.summitracing.com/egnsea...view=sku#rstop
----------
ls1 is a gen III motor, u can filter that on summit....

 

http://store.summitracing.com/partde...0&autoview=sku here is a good cam for ya, works with stock convertor and everything..... take off the lk on thos part numbers i gave ya b4 sorry

 

Those aren't voodoo cams...those are their normal hydraulic roller's. It appears that the voodoo's were only made for the 1997-2002 years.
----------

Hmm...no, that's not bad at all. Mild enough for a daily driver and yet still fairly aggressive.

 

Damn automerged posts...grr.

Anyway...I don't know why, but ever since I found the Voodoo cams...I've wanted nothing but one of those in my car. It's irrational...I know.

 

yeah that one i just gave u the link for is a voodoo cam, i got the number for it out of my lunati catalog and it lists it as a voodoo cam, summit just doesnt, and yeah that first link was just a bunch of cams.....the discription says it gives it a good milage and torque increase....

 

Hmm, just downloaded Lunati's catalog and you're right, that is a voodoo cam. I wonder why Summit wouldn't identify it as such?

 

Very nice Camaro. I wouldn't mind having a first gen in addition to my 3rd gen.
