Summit Cam Help/Recommendations

no quality problems
but you do NOT want to use the 272 cam- it's way too much duration for a low compression motor
the other cam having 218 @ 50 but really wide 114 LCA

the 204 214 278 intake is similar to the 340 cam note the long duration for not much lift
actually all have long duration for the lift which kills your bottom end and mileage especially in a low compression motor
you can get 450+ lift with a 256 cam it's aea under the lift curve you need not duration
get a big peice of paper and draw a circle and map the timing events IP IC EXOP EXC of all three

If your car is stock gears, stock converter and low compression I'd pass on all three
throw a new timing chain on and be happy
save for a lunati voodoo 250
