I have a friend with this boat. Has twin 500hp's in it and we are going to put new valve springs in it. We are talking about adding a set of pro chargers too. My question is does anyone run a methenal injection kit on their boat? Was wanting to put this on both engines to retain using pump gas and keep it from detinating. I've had great luck using them on cars with 14 psi and still able to use pump gas along as it had a kit on it. Droped the air intake from just over 200 degrees down to 94. Any insight would be appreciated. Thanks!!

Do yourself a favor and when you're doing
the springs, replace the lifters too, otherwise,
you'll be replacing those and the cams
shortly afterwards when a lifter breaks and
wipes out the cam.

I've seen this happen before by just repacing the springs
on those engines .

Thanks for the advice! Will do that also.

I use the Moral lifters and Isky springs.

I used that same combo in mine too.

running hot skater uses the meth set up look him up here.

Does anyone have the part numbers for the valve springs to use and lifters as well. We need to get parts in the next few weeks to get this boat ready for the summer. Thanks!
