408 cam / build help.

David66dart said

I am building my second 360 motor which will be a 408 stroker. I am 17 and experience is limited. The blocks I have are a 1971 block (30 over) and a 1977 block (30 over) block preference? I have some 77 heads with 1.88/ 1.6 valves I will be using, i will be doing some porting. anyone have ideas on what cam to run? Gears are 355 with a 904. In a 1966 Dart 2 door. Aiming for 350+ HP 400+ TQ. On 93 pump gas

Block to use?
Simple!
The one that sonic checks the thickest!!!!!!!
“Some porting?”
Are you going w/a 2.02 valve? Touch the entire port. Widen it as much as possible. An engine of that size wants to breathe better than an OE head delivers.
A cam that will make 350 HP and use 3.55 gears? Well, that may depend on how well your heads flow. The above cam is good. If your heads move some decent air, you can step down to a [email protected] or less and make that power easy! Between the cubes and decent head air flow, you’ll do it EZ!

I have seen stock headed 360 engines make that power and more with a stock 340 cam and headers. (FWIW, Also coupled with a rpm and a 750.)

I’m using a Hydraulic roller at 224@050 in a 360 with tti headers and well ported heads. A great street cam that’ll deliver good hp for sure. OH! It’s a 904/2500 stall w/3.55’s on 26 inch tires. 67 Cuda.

You got this!
