cc306 with 5.7 rods how will this cam do? Ive heard of cams rubbing on rods too.

 

I've never heard of a cam rubbing on a rod.. maybe the rod being too long and the lift on the cam being too big making the valves to colide with the piston heads, but from my understanding a couple mechanics told my buddy a CC306 would work nicely on a 383 due to the high duration. Not sure how much validity there was in that advice.

 

cc 306 is a decant cam but you can make more power with a much broader rpm range if you go with a custom grind, especially if you have any head work done. I would check out either Lloyd Elliot’s or advanced inductions cams, either of those are making really nice #'s. And I wouldn’t worry about the rod hitting , concern yourself with the piston to valve clearance, that is where you can run into a problem sometimes.

 

actually some rods will not clear the cam...thats why they make small circle base cams. they only way is to install the cam or ask the manufacturer if it will clear the name brand or custom cam you got from someone else.

oh yeah...that cams too small for a 383. i think its just about right for a 350/355 but thats just me.

 

i have a 306 in my 383 with 6.0 rods and they have no issues with each other.

 

I'd get a custom grind.

 

What size are our stock rods? And where can I get a cheap 3.750 crank? Doesn't need to be forged just a good one for around 300 or less if possible.

 

Buddy of mine has a 306 in a 383. CNC LT1 heads, 10 bolt rear, M6 tranny. Electric water pump and SLP 2otl catback. Made a somewhat peaky 401 rwhp. I'd get a different cam.
