Here's my first contribution/request for thoughts.
First, what I envision. 387..call it a 388 stroker motor wanting between 10-10.5:1 compression. It might go to the track once or twice in it's life, more daily driver, weekend cruiser, with the ability to smoke the tires on the way to work if I want.
Now what I have.
Block-360..will bore to 4.125 to accept (cost effective)Chebby pistons. An Edelbrock($Broke$?) top end--Air gap intake, 60119 aluminum heads, timing, and two Eddy cams 2132, and 7132.
Which brings me to the crank. A 390 that I'm thinking of having offset ground to accept the 2.2 chev rods(again $ effective) If I'm thinking correctly, when offset grinding, you add the differance to the stroke...yeah? 3.574+.048 (2.248-2.2)= 3.622 stroke. Or Am I doing bad math somewhere?
OR..while spending hour after hour searching for connecting rods miss a custom manufacturer that didn't want 4-5 times the cost of the chev rods. I can pick up a set of2.2 forged rods for about $275.
