2 Bolt Block

[Jimmyzw22]

Hello, I am new to this forum but been a mechanic all my life.

I am currently doing a frame off restore on a 1974 corvette that was my fathers. He passed away two years ago and I inherited the car. He was going to do this when he retired so I am fulfilling his wishes. The car will pretty much be driven only to club meetings or shows so here is my questions.

When I got the motor apart he apparently had some work done to it as it is only a 2 bolt block and not the original one. It is currently .030 bore. It did have a nice B&M tranny though. So back to the question. I plan to build a 383 stroker, already have a nice set of AFR 210 eliminator heads complete and ready to go.

Should I get a new 4 bolt block and start fresh there or should I have splayed caps installed and go .040 on the bore. I am on a tight budget but the motor needs to be built right. The plan is to have about 500hp and a good shot of nitrous with it.

What direction should I go on the block? The frame is heading to powder coat next week.

Thanks in advance

Jim
