To many variables to make any recommendations without more info. Do you just want a nice cruiser or are you looking to run 11's at the track or something in between?

Looks like it will be a 355 if you keep the stock crank. Could have done a 383 with a balanced kit from Comp. Products for under $800. If its a 355 then a set of dished pistons for a 9.5-1 compression with a set of 64cc heads. A set of vortec heads 906 or 062s with the stock springs or a set of Z-28 and a Comp. EX-268 cam and lifters. This is a great set up with stock trans and converter. I would step up to at least a 3.42 gear set.

I like SRP pistons. For a 355, use a 2 valve relief flat top piston and a 64 range cc head. For a street small block, a 180-195 cc runner head is good. If you can swing it, a hydraulic roller is best, but without knowing some specifics it’s hard to say. But for mine with power brakes I used the lunati 60112 .535/.550 231/[email protected] hydraulic roller.

You guys are great. Also have helped me in the past. Thank you again. Sorry I had not provided enough variables. On a family budget first. Going in the 82’. Would love to be a daily fun street car. No racing in mind. Mostly cruise around and love a good sound to an engine. Not worried about 11 second car. Just want it to perform good. I have a 72 Cutlass supreme that I can do the fun stuff with. This elco has been used in a few gambler 500’s. Loads of fun with great people. Again thank you so much to all in this forum.

I've been using Northern Auto for 20 years, great people - You can't go wrong with their Master rebuild kit and they let you upgrade the parts you want.

If a crate engine is a option consider the 350/290 from GM it dyno,s at 308 hp. Super chevy did some bolt on,s and made 333 hp 370 tq that is all NEW from GM with 3yr / 50 k warranty ! If your going to go the build route theirs a few things to keep in mind. If your going with a auto trans dont over cam , theirs many articles on net to bring you up to speed on valve lift, duration , overlap. Second keep compression ratio 10;1 or a little under this will allow you to live on pump gas without any octane booster or having to retard your timing . Third if your willing to shop around a little theirs great deals on used parts for SBC on craigs list / facebook market place !
