Hey guys, I value the opinions of all of you, so here goes. I'm in the process of a major re-detail of my 69Z. The car is numbers matching and very correct, other than the CE warranty block. I opened it it up to give it a look and the #7 cyl was cracked. It turns out this engine is not a CE 302, but a CE LT1-350. I guess I knew that. It has all the correct parts for that motor, 010 block,including TRW pistons and 6th design rods. The crank is an "1182", which is a forged steel unit. My use of the car is weekend cruising, no racing, and the goal is to keep it looking factory bone stock(technical specs/appearances). Right now, it's very close. Here's the question. Since I have all the tin, correct 69 -186 heads, original carb/manifold/alt/distr/exhaust, and all the smog stuff, what do I do? All I really need is a short block. Do I now build a stock 302, which means find a crank/pistons and a block, or do I drop in a street 350, or do I go 383, and hide it all under the factory look. I'd also like to keep the same -186 heads. Since I do not have the original block, the value of the car will not likely change much. It will certainly never be original, but I want to stay with the factory restored theme. What do you suggest? Will a 4:10 stress out the 383 if I go that way? My 16 year old says go for power, since it's not original anyway. I can still keep the factory look regardless. Comments?
