Hi guys,
I have a 70 Torino that I'm building a 429 Cobra Jet motor for. The car weighs around 4000#. The motor will use the factory CJ heads, 72 CC with 2.24/1.73 I,E valves and 1.73 stock rockers. 735cfm Qjet carb on factory CJ intake and run on pump gas. Factory exhaust. Bore is 4.39 (.030 over) and stroke is 3.59. 9.5-10/1 compression. C6 automatic with 2500 stall converter. 3.50 rear gears with 26.5 in tire.
I want a cam that is hotter than factory and will work well with what I have for a good street beast. Has to lope good too.I have narrowed it down to these 4 cams but if you have a better suggestion by all means share.
Comp Cams XR280HR: duration @ .050 I-230 E-236, lift I-.521 E-.532, LSA 110, rpm 2200-5800 (roller cam- not sure I want to go this route) I like these numbers tho
Crane Cams H-288-2: duration @ .050 I-226 E-230, lift I-.522 E-.530, LSA 112, rpm 2400-6000 (hydraulic flat tappet)
Comp Cams 280H: duration @ .050 I-230 E-230, lift I-.530 E-.530, LSA 110, rpm 2000-6000 (hydraulic flat tappet)
Comp Cams 287TH7: duration @ .050 I-234 E-249, lift I-.519 E-.503, LSA 107, rpm 2200-6100 (hydraulic flat tappet)
Thanks!
Jim
