Hi, I am new to the website. I have owned Camaro's since I was 16. I have a 89 IROC-Z 350 TPI. I have some questions on building off my 350 to 383 stroker. I do not know everything about cars but quite enough for a chick. I am not ignorant about cars. My camaro is not stock as I have the Edelbrock shorty headers and I have a high performance rear end with 3.73 gears switched from 2.76 some (Australian rear-end) I have Edelbrock rpm series exhaust and little minor things ect. Any info would be helpful.

Thanks!

 

What are your 383 questions?

 

To tell you the truth, I think you might want to do a new engine on the side (get a truck engine from the junk yard). For a 383, a 4-bolt main block would do better for you. Machine work would be needed to bore out the cylinders to 4.030 (0.030 over) and make sure the block is good. A good cam would help as well to help the engine breath. With the cam, you would need to replace the springs on the heads and get new (screw-in) rocker studs (stock studs are pressed in and usually can't handle the extra cam lift). Stock rods are good, but the crank would need to be changed to a 400 crank. Make sure you get your parts before you bring the block to the machine shop because they would need to do work to make sure everything has good clearance. A good block to start with is one out of an 87 or newer chevy truck. That way you can choose a roller cam or flat tappet cam and not spend tons of money on retrofit lifters. With the roller cam, you will need to get a blocker plate to hole it in the block or the cam can walk out. Any questions, PM me.
