Looks like I sold my cam to Vette!:p :D

I've heard of swaping 4/7 on roundy-round motors because the left side runs leaner(always turning left)Now you've got a 4/2 combo on the right side?For a efi boat,doesn't seem like it would matter.
Bobby,you obviously have a engine shop.I'm interestsd in your cams.Thinking about building a 540.These free forums sure are expensive.Bob

Thanks for the responses!!
 

Looks like I will go with the Erson with the 4/7 swap. It helps that JDNCA1 already has this cam new in the box since he decided to go with Schubek cam and lifters in his 632. I have always had good luck with Erson on past motors. Now I have to start looking at head options. You guys think 400 CC runner Big M's are too much or good for the 598?
Thanks,
Craig

Craig ,you know the drill ,what rpm ,but really the new AFR heads blow away the others period execpt the big cheif style
The Exhaust flow is killer on the AFR's

WetteVette,
How are the Shubeck lifters holding up ?
