what the best Length for pushrod with 205 AFR heads 66cc , GT11 CAM , STOCK LS1 BLOCK

thanks

 

Buy a $20 pushrod checker and find out yourself. You have the variables of the cam, heads, gasket thickness, what lifter used and how far the pistons are out of the hole; too much for anyone on the internet to know. I can tell you the AFR heads typically use a smaller length pushrod than stock heads.

 

Don't guess, I did and when I did finally check, I was running .130 preload, way too much.
