Hey guys, I'm thinking about buying an f-body for really cheap next spring then building the engine up into a monster. I know I will need a forged bottom end if I plan to run a s/c. My question is, if I build the LT1 up with forged pistons, 9:1 compression maybe, will it still perform well before I slap an s/c on there? I probably wont have the money to put an s/c on as soon as the engine is built so I was wondering if it's ok to drive it with low compression even though I don't have a power adder. Thanks guys

 

as long as you have some good head work and cam to make up for it. it will most likely run better than a stock LT1 motor. depending on how much boost you want to run you might want to go a little lower on the C/R 8.5 so you can boost the crap out of it My buddies S/C formula ran a 8.30 with a close match to a cc 306 cam but more sutted to a blower and a little less than 9.0 CR slighty ported heads too. and ran 7.50 with the blower on it but it shows 12psi on the guage at 6k rpms. but its a 6-8 lbs kit Just make sure you are going to get a blower if you build a blower motor.

 

Wow, thats amazing, I was actually wondering the same thing today and was going to post about it. I am wondering how a s/c custom cam would drive N/A? How much power would it be sacrificing?

Soooo...TTT for us

 

Will I need a forged crank too? I'm hoping for around 480 boosted rwhp, will a stock crank handle that?

 

anybody else?

 

Depends on how much you want to spend. They say that a Scat 900 crank is good for 700 HP, but if I was going to build a blower car pushing over 500 HP at the crank I'd watn the extra $300 insurance going with a forged crank over a cast one.

Your goal is to build a sweet blower car. Therefore, IMO, don't compromise on what will make a decent non-blower car for the time being. Build it all-out blower specs, and just put up with it until you get the blower. Don't sacrifice power on the blown side just to have a bit more before you get the blower.

JMHO!

 

You make good points. I'm for sure gonna build a blower engine, and I'm not gonna sacrifice power on the blown side before it goes on. I was just wondering if it will still run at least decent before the blower goes on since it will be made for a blower. If not, it will just sit in my garage until I can get the blower on too since this will be an extra car.
