I have a 94 Z28 with a tired LT1 in it. Iam thinking of putting in a 383 or a 4bolt main 350. any help?

 

The options are many. You could do a budget 355 or 383 for a reasonable amount of money and deffinitely wake the car up.

Do you have an ET goal of HP level in mind. Is this an A4 or M6 car?

What if any mods are currently done to the car?

 

you wont need 4 bolt mains unless your planning on making more then 600rwhp. first set your goals then go from there

 

well im looking for about 400 to 440hp. I was told that she is running about 300hp right now. even as tired as she is i still took a 2004 mustang GT for a 1/4 mile 105mph. i think he is still back there.LOL thank guy for the info.

 

she is an A4 it was just rebuilt a month ago. but i was thinking of putting in a trbo 400. i dont like the th700, that much it feels funny when shiffting gears.
like it mite fall out. for the money the guy paid to have it rebuilt i could of bot the trbo 400.
