Ok my 89 irocz has a weak 305 tpi in right now. I bought a 383 about 8 months ago an plan to put it in my camaro heres the specs on the 383.

cast 3.75" stroke crank
6" eagle H-Beam rods
KB hyper Domed pistons
11:1cr w/64cc heads

It has not been built yet I am waiting on my tax returns to buy heads. I plan on using AFR 195cc L98 heads,roller cam in the .525" lift and 292* dur range you think that is ok to use for a semi-daily driven street car that will be raced on weekends? These are the items I realized I would need to make this project possible.

58mm throttlebody
36# injectors
350 ecu
higher stall tq converter
lt1 starter to clear my headers

anything else? Also should I go with a forged crank I expect this 383tpi to make 450 lbft of torque at the crank with the proper cam of course! anyway feel free to leave a message if you think you have a better combo for me let me know Im open to suggestions Thanks Johnny.

 

are you just gonna replace the TB and injectors on the stock TPI unit? the stock TPI setup will really choke an engine like that

IMO you should look into an aftermarket TPI setup like the HSR, superram, or something similar.

 

Yeah I do plan on swapping the TPI setup to the HSR once I get the motor tuned. But that wont be for quite a while I expect to get this motor in my car by summer 04' Quite a ways away but it will take time to get all the parts I need for the swap.

 

My advice is to take your time and have fun.
