Here goes nothing!
I got a 68 383 block that was rebuilt with new bearings, 9:1 pistons, bored .030.
I got 452 heads, a tunnel ram, two 600 Holley carbs, Accel distributor, and misc other parts.
I still need a bunch of parts, including timing chain, cam, lifters, pushrods, rockers, and an oil pick-up.
The goal is to pull the stock 383 and replace it with this engine, which I won't be so concerned about blowing up, although I do want this engine to run well.
I considered different heads, including the original ones on the car now, and decided on the 452s because they will work with unleaded gas without extra work/cost, they are in good shape and were at a good price.
I am not sure if they will work well with the rest of the combination, but I am told they should.
So, I have a few issues to sort out:
1) What cam/lifters/pushrods would work best?
2) I'm going to pull the valves out to check them out and put in new seals, can I use the stock springs, or should I get different springs?
3) Is a stock timing chain a good selection?
4) What rockers should I use?
5) This is a 4 speed car, and the crank is not drilled for the input shaft. Taking the crank out to bring it to a machine shop and have it drilled out is not ideal for me, nor is bringing the entire engine to a shop. Can this be drilled out at home, using a jig of some kind and/or a drill press, or should this be left to a machine shop? (I will not be cutting the input shaft!)
I'm not a complete idiot when it comes to engines, I'm just not experienced in the selection of parts to make a combo work well.
I will be getting a new clutch and headers once the engine is sorted.
I need some direction and input to get this done- Help me FABO!
