I'm in the process of selecting a cam and would like your input on a few things.

Heads are Lt4...here's the flow #'s

intake 137.6@200
198.9@300
239.3@400
272.2@500
298.1@600
295.8@650
293.6@700

exhaust 109.5@200
148.1@300
178.7@400
199.6@500
214.1@600
218.9@650
223.8@700

intake valves are 2.080
exhaust valves are 1.600

409ci Lt1
Eagle crank
compression ratio is 10.9:1
K&N cold air kit
58mm ASM TB
intake is Lt1 port matched to the Lt4 heads
hooker long tubes 1 3/4"
gears are 3.42 now but will probably be going with 4.10 soon

I'm planning on going with a hydraulic roller cam with the following specs:

intake duration 234@.050
exhaust duration 242@.050
lsa 110
lift 612

The car will predominantly be driven on the street but will not be a daily driver so I'm fine with leaning towards a more aggresive/less streetable setup. I want to stay with a hydraulic roller...what do you think about the cam specs and what kind of horsepower can I expect. Will the factory fuel system with a supplemental inline pump and an adjustable fpr be able to handle it? Should I get a stud girdle?

Thanks,
Jason

 

for one those are some good flowing heads! For two was that LT1 intake machined to fit the LT4 heads since it wont from the factory? Also the cam doesnt seem to have to much that would cause it to be non streetable but if you want something that will match your setup and perform well with it go custom grind. I was going to go off the shelf but the guys here and on other boards talked me out of it.

 

the cam specs are the suggestion of a custom grinder...who says that I shouldn't go any more aggressive with a hydraulic roller

 

Hey Jason, how did it end up working out for you?
