I’m not building a 1000 horsepower motor, and I actually don’t even care if I lose power because the sound matters more to me. This is going to go into a 1968 firebird and I’m only looking to drive it. Should I helicoil it or tap it to metric? Im not putting a new crank in it since I’m not looking to break the bank and I want this engine done soon as possible. Bonus, I stripped some threads in the crank since i don’t believe the crank pulley bolt was long enough even though ARP said it was meant for a sbc, so I’m a little worried if I put a tool in there it’ll do some more damage. Can I get away with the factory rockers and hardened pushrods and new lifters? This isn’t a race situation, I just want to be able to drive the thing for a decent amount of time with a nice idle. This is what I don’t know, should I buy all new rockers that match the push rods as well? The engine hasn’t been put in the car even and came out of the crate not too long ago. If I did buy this I do realize I need the better springs and I would buy some hardened push rods.

It has a carb so no worries about it not working with injection. It makes 250 hp and 350 lbs of torque (its a truck motor because it was decently cheap from ATK). I have a 1987 sbc 350 that I’m going to put in my 1968 firebird. I want to know some peoples opinion on this since I have no idea about this stuff and I’m very inexperienced.
