Im currently in the process of building a FI motor for my OFI kit. Im going to be running a TC76. The car is going to be a daily driver and it will see a roadcourse once a every month or two. With the budget that I have set I have two ways to go with the longblock and I cant decide.

My plan is to make AT LEAST 700 rwhp. The more I can get the better.

Here are the two options I have chosed.

1) 347 with AFR 205 or 225 heads

or

2) 383 with Patriot LQ9 heads

So which one would you choose?

i would take smaller displacement with the thicker deck head .better smaller displacement than 383 pushing water

Why not do a forged LS2 stock cubes as it's the same price as the 347 and you'll get the bigger bore.

383 lq9's will work get to 700hp and better heads are easier to change than the hole motor.. either set up will make 700.. thats pretty much what i'll be doing this fall, i have a good short block and just gonna run my lq9's for a lil bit and they will still make plenty of power for a street car.

Im not going with LS2 because I already have the LS1 block and stock crank. Got it for free. Plus I am a diehard LS1 fan.

I guess I can always update the heads on the 383 but I dont want to keep pouring money into the car. I just want to do it once and be done with it. Plus I have some exterior mods I want to do in the near future.

**** if can do it all over again I would do a 370 ls2 and about 16 psi. The crank is good for high hp, I would change the rods and pistons and ARP everything in the bottom.

ARP everywhere and forged parts are a given.

I concur the thicker deck head will be better with FI.

Smaller cubes works better.....

That 76 would like that 347 better too. I'd go small motor and better heads any day. You can still make the power with it.

Thanks for the input everyone. More is always welcomed.

Ill start a thread once I get close to having all of the parts.

Out of those two options, I would go with the stock cubes and AFR 205 heads. The 225 would be wasted money on the setup IMO. They money difference could be applied elsewhere since you are on a 'budget'.
