Can anyone tell me the good and bad about the 367 chevy small block? Also what size jets should I use with this setup:world products sportsman 2 heads(2.02,1.60), holley 750 card, msd box, hei type distributor, tall victor jr. intake , flat top pistons. I also need to know a spark plug reccomendation and gapping information. Timing will be at 34 degrees total advance. I would rather be too rich than too lean. Thanks in advance!

Start with .040-.045 plug gap, in a heat range of 8 (for NGK, anyway). As far as the jets, it really depends on your carb's true performance numbers. They all flow a little different, but you might want to start with about a 94 primary and a 96 secondary. That's richer than what I run with my Gaerte carb, but it's a lot better to start rich than lean.
As far as the 367, I don't know what kinda crank/block combo it's got so I really can't help much other than to say that a 400 block w/ a smaller crank is better than a 350 block w/ a bigger crank as far as durability and high end power. The 350 block w/ the bigger crank will give you more torque, but be less durable in the long run.

Hope it helps,

the block is a 350 with 4 bolt main. Six inch eagle rods, manley lightweight flat top pistons, forged steel 3 and 9/16 crank. I have a set of sportsman 2 heads(dart) with big valves. Victor jr + 1" intake. Can you tell me some difference between this combo and a 377 or 383? thanks for the reply!
