I have an 86' iroc 305tpi getting a cam kit with a lift of.420in intake and .442in/exhuast a duration of 268 intake and 278 exhuast, and was wondering if anyone knows if this is a good cam for my motor. i have a ported plennum,runners and intake. Have headers and dual exhuast.

 

i have the same cam, im also adding 1.6 rockers im planning onmaking power from 1500-5000

 

Sounds like a Nice mild Cam that wont require much further modification to work well.

 

replacing the peanut cam eh?

Sounds like your getting the Summit/Crane Blazer cam. I ordered the Crane Powermax 2030 which has about the same specs. I had to return parts to my local speed shop and the 2030 + CRANE FPR was a even swap.


Need to get it installed. Should be worth 30-35 hp alone, + another 10-15 from porting the base/plenum.

 

Ack!

Your name is unacceptable!

 

I would go a little more aggressive, I am running a compcam.
.495/.503 218/224 and I wish I had gone bigger than that. The stock heads will hande up to around.470, I would look at something around there.

i got that cam in my motor but i wish i would have gone with some thing a little bigger cuz that's that bearly bigger than stock lift on a 350 but it might turn out go on a 305 try maybe a little bigger.

 

I had a cam virtually identical to that one. I ran 94MPH in the 1/4 with it. Personally, I'd get one just a little bigger, something with more lift. Or maybe do some 1.6 rockers, that might help.

 

My 305 cam was 440''/454'', dont remember duration, ran great with 96-8 mph in the quarter. I recomend it
