4/7 Swap??
I was reading up on the 4/7 swap on cams to change the firing order and gainng up to 10hp.....was just wondering if anyone has done this and what they though about the results...

Re: 4/7 Swap??
LR's post in the latest thread:
Hope that sums it up for ya. 
Ya won't see 8-10FWHP on the normal LT1. What Darrin is refering to is a 8-10 gain on a 1000+HP pro motor.
If ya got a 500+FWHP engine ya will see small gains but it is NOT an automatic 8-10 HP just with a cam change and a 4/7 swap.
IMO it's NOT worth the trouble or expense to change.
