I have a 01 cav stock car I run at a local 3/8 highbanked asphalt track. I need to squeeze atleast 10-20 hp out of this thing to take out 1st and 2nd place a toyota and a honda of course. I'm tied for 3rd . I just sent out the head to get it shaved and found out that web cams won't have a cam for me for atleast month. the season will bee allmost over by then.Any body got some connectitions or ideas .
its the OHV 2200 motor and "No I can't use a twin cam" thats a different class entirly.thanks
any tuning the computer allowed? there is always Hptuners software. give us more of your class rules. there is always intake, tb upgrade, header etc
Im a Xbox 360 fanboy...and damn proud of it!!
thanks for replying,
basically it needs to look stock ..headers and an intact may be to much, but computer tweaking sounds like a good idea or my be a stock looking performance tb.
A big bottle neck for power on the ohv motors is the head.....since it's out getting shaved get it ported and then tuned with the hpt and you should be happy with your gains. also look into swaping in the 1.6 stamped rockers out of a sbc since the factory rockers on the 2200 measure out to 1.54 to one......

excellent advice.
you will get good results from this, also with the head off, think about a thinner head gasket to boosy up compression a bit.
I would recomend a re-grind cam over a web cam though. They are NOT billet core cams.
Who has or does the re-grinds I don't have any specs to take to a machine shop. the head got shaved .030 this should take things to 9.6:1. not sure what the hp would be but hoping more than the 115 stock.
what about exhasut upgrades? or atleqst get rid of the cat and resonator? just throwing that out there? not sure if thats legal for your class or not
what are the rules for the class? if DOHC isn't allowed, i take it SOHC is?
and by SOHC i'm referring to the honda and toyota you're going after.. I'm pretty sure neither company makes pushrod 4 bangers
I think the rule is factory-stock appearance in this case.
Go beyond the "bolt-on".

CRANE, COMP, CROWER, ETC....THEY SHOULD BE ABLE TO DO A REGRIND FOR YOU, AND HELP YOU FIGURE OUT WHAT WOULD BE BEST FOR YOUR APPLICATION.
If you shaved your head that much, you will need custom-length pushrods.
Go beyond the "bolt-on".
Uh, JUCNBST: I believe you mean the rockers found in the LS-series engines, since in '98 the LN2 went to cast roller-fulcrum style like the LS V-8s have.
Go beyond the "bolt-on".
^ If he wants to run the stamped rockers or roller rockers you have to swap the rocker studs out........I cant even remember what the crane part number is but I did find it in an old thread by madjack....hell I even have the rocker studs from crane in my garage some place. If I find them this weekend when I'm working on the mustang or cavi I will post the part numbers up.
let me know what ya come up with i'd really like to get a cam. we shimmed the rocker studs and springs, seemed to worked out great . the plugs appear to be a little on the lean side though. any body got some injector suggestions.
