Hello all. I've been researching for a while on here and other sites, and I figure I'd finally tell about my build and get some advice from the pros.
Overview:
Vehicle - 1947 Chevy truck, M2 front suspension, dropped S-10 leafs w/8.5" 10 bolt w/ 3.42 posi in rear. Going to use an S-10 T5 (haven't gotten yet) and around a 28" tall tire (225/75 or 235/70 on 15x7)
Engine:
1972 250 inline 6, which is at the machine shop getting freshened up:
- .040 over flat tops (~9.3-9.5:1)
- new bearings/rings
- lump ports installed in the head with 1.94 valves
- new oil pump, timing gear...
-Offy 4bbl intake, Holley 600 carb, Flow Tech headers (1.5" primary with 2.5" collectors
But I'm torn between two different cams for this combo...
-Crower 03242 Level 3
lift intake - 0.478
lift exhaust - 0.490
adv dur int - 262
adv dur exh - 272
dur @ .050 - 204
dur @ .050 - 212
lobe center - 112
rpm range - 1800-4500, peak of 5000
Comp 268H -
lift intake - 0.499
lift exhaust - 0.499
adv dur int - 268
adv dur exh - 268
dur @ .050 - 218
dur @ .050 - 218
lobe center - 110
rpm range - 1200-5200, peak of about 5500
I'm leaning towards the Comp cam, especially since it comes in a kit with everything that's needed, for good price too. I'm shooting for about 250hp and about 275ft lbs of torque. Will that get me there?
Thanks,
Wayne
ps, here's a link to some pics from last fall when I was test fitting some body parts after the suspension was finished and engine was in it.
