I think I might also chance the stock came to a stage 1 RV. If any one has any input, I am all ears. I can't spent allot of money and am looking for a low budget rebuild so it will pull my 32' trailer (12,000lbs dry weight).
Thanks for any input
West Jordan as in Baja Salt Lake City?
These are the famous or in--famous Swirl Port head. They are a great grunt head and work well to about 4000 revs.
Presuming this thing has TBI injection, they will take to a cam up to about a duration of 200 on the intake and 215 degrees on the exhaust with 110 degrees or more of Lobe Separation Angle (LSA), not to be confused with Lobe Center Angle (LCA). LSA speaks to overlap which you don't want for this set up, LCA is the middle of the lobe duration. You need to be careful about the timing gears and chain. OEM and OEM direct replacement timing sets are indexed about 4 to 6 degrees retarded. OK for emissions not so much for giddy-up. You want an aftermarket set that's at least straight up, better if adjustable as around 4 degrees advance will pick up even more bottom end for ya. The chip might like a change, but a slightly bigger cam with a lot of LSA will hold up the vacuum which is something TBI really likes, so you might get away with it. you'll see when you get there, if runs fine call it good, if it's a bit ornery then a chip. It'll run with your changes just maybe not as smoothly as you'd like, then you "tune" it. Lots of places blow custom chips if you need it, just a GOOGLE away.
