I have a 33 Challenger offshore. It has a DDC hull and a 9ft beam. I am impressed with these engines. What do you have? Dwight

I have a Fountain 29 Fever that I really wanted a single 525 EFI but I was made an offer I could not refuse! I must admit that I love the twins and hope to get just a bit more performance without too much investment...right!! Gary

Cat and Mice how much do you want for the rocker arms? and would it be any problem installing on the 6.2 vortech heads? What power do you have now? Thanks Dwight

You need self aligning rocker arms for the Vortec heads.

Will the rocker studs be ok with 1.6 rockers? Do you recommend a certain brand of rocker? thanks

Most mfgs. make rockers specifically for the Vortec heads. The stock studs are fine in my experience. Where you run into a problem is the retainer hitting the valve guide at maximum lift. The stock 6.2 cam has .465 lift. On the heads I've checked this is about the maximum lift before an interference problem. So, the 1.6 rockers may not work without machining the guides. The 6.2 cam has the same specs as the crane 2032 cam just for the record,.452/.465 lift, 214/220 @ .050 duration.

Thanks for the help. Do you have a brand of rocker you like over another?

TTT,,, I'll be back when I have more Time

Whitey,, On the K&N site, I found the Part #59-001 but not a IA59-5001. Is it the Same?

I have the 6.2's in a 32 Sunsation and LOVE them! I added IMCO exhaust but everything else is Stock!! I am "VERY" interested in any ADD-ON'S that any of you have tried and liked!!

mama tryed:

What type of improvment did you see with the Imco exhaust? Also, how much was each system and did you do the work yourself? Like to know what your setup is like, i.e. props, drives, drive ratio, etc. when you have time.
