9:1 static compression with stock dish pistons
252H extreme energy cam(212,218@.050 .447,.454 lift on 110LSA)
1 5/8" headers with 3" collector
edelbrock performer intake
650cfm carb
Mallory distributor... blah blah blah

Now here's something I wanted to experiment with...

I have a 1.52 ratio roller rocker which makes .453 and .460 lift but I was wondering what the 1.65 rocker would do for power... it would make .492 and .499 lift. Thanks for the help. I predict a torque monster!! either way!!
Well the short rods suck to be honest.
I have a 55 gallon drum about 1/2 full of the 5.565 rods.
I would run a 5.7 or 6.0 rod to get a better rod ratio.
The better rocker arm ratio will help to open the valves quicker and make the cam appear a little larger.
The down side is the extreme rocker arm ratio really puts exta pressure on the rocker arm stud.
If you don't have screw in studs and just have press in studs I would never try it.
It would make a great engine for a tow vehicle.
