Re: 232/236 cam in a ZO6...advice That's just too damn big! U can get the same power from the comp grind 54-428-11, specs out at 228/230 571/573 112. Made 413 rwhp, cam was also recommended by David Wizards "cam doctor". He said the with ported heads-"look out!"

Re: 232/236 cam in a ZO6...advice That is a large cam for a stock motor Z06. You can make the same power with a much smaller cam, better idle and drivability. Even a cam as small as 224/224 can make over 400 rwhp on stock Z06 heads, but I would go with more lift even on the stock heads.

Re: 232/236 cam in a ZO6...advice Vettes are tricky for idle control. Much more so than F-bodies. That is the limiting factor. The specs you listed will make great power especially top end power but I think your peak will be a little high. If you kept your intake duration around 230 on 112 that would bring your peak down around 6300rpm.
Cheers,
Chris

Re: 232/236 cam in a ZO6...advice We offer a 232/228 reverse split camshaft that makes good stock head hp, but you might also consider a 228R. I had the 228R camshaft in my vette & it started & idled fine with some tuning

Re: 232/236 cam in a ZO6...advice If youre hard core youll like the cam. Driveability is gonna suck but if you adjust your drivin style its no big deal. Its just a matter of keeping the rpms up. My 230/114 cam idles fine with stock tuning. It even runs with the A/C on.
Is that cam gonna work with stock springs? Id think it wouldnt since the motor will be revin to 7k. Still you got the light weight valves. What do you guys think about a 232/108 cam with CC XEr lobes

Re: 232/236 cam in a ZO6...advice Vortech,
Is that a book by David Vizard or an online article? Where can I find it? Sorry to change the subject, just wanted to know.

Re: 232/236 cam in a ZO6...advice Speed Demon, I read this article in a Muscle Mustangs tech guide. David Vizard recommneds that u use this guy (Denny) at Motor Machine & Supply. Apparantely he punches in the #'s in a one of a kind Cam master program and gets the the perfect specs for a cam with ur driving requirements. this is after u give him the flow figures of ur heads as weel as the bore and stroke, compression etc. Apparantly all the top races use this service. Anyway the cam i have in my 02 is perfect except for the centerline, Denny suggested a 108-BUT he said when the heads get ported a 112 will be awesome. If u want I can fax u the article if u have access to a fax machine-or i'll try to scan it an email it to u. If David Vizard recommends him then he must be good.

Re: 232/236 cam in a ZO6...advice Dude, I have a little C1 222/222 .566/.566 112 LSA cam and I have all the power I nedd in a 3028lb car.
I've raced juiced f-body's (dry shot), Vette (wet shot) and 03 Cobra's (pulley and stock)on the freeway and have yet to lose. Not to say that I won't, or that i'm the fastest out there. The C5 with a 100 wet shot would have beat me if it wasn't an A4, or if we went from a dig.
My car can be daily driven without any hot start or surging problems.

Re: 232/236 cam in a ZO6...advice thanks for reply(s) and suggestions...I am a little worried about the duration also (surging etc) and am now looking more at the C2, TR224, or something close to those specs..

in the october 2k3 issue of gm high tech performance, david vizard has an article about cams, and stresses how good motor machine and supply is. its on page 48 for those who havent read it, its a very good article.

Re: 232/236 cam in a ZO6...advice This is determined by head flow status and cam duration. For example my combo flows 285cfm with a LS6 intake bolted to the head at peak cam lift, my cam is .585" lift 220* duration on a 112* lobe seperation. It made 404 rwhp at 6200, difference with bigger cam combos is how faT PEAK IS. My peak is pointy where other combos with more cam are fatter in this area. I think intake manifold design sets peak rpm range most of all. Ls1 is very versatile with cam choices but big peak power will be traded for poor under 3k rpm response/driveability. Gears are the big equalizer for big cam choices, imho stock LS1 needs 4.10's to be right, 230*+ cams need 4.56+ gearing .

I made this with an X1, lt's, pulley, borla catback, and high flow cats. Wonder what it would do with an offroad pipe and more aggressive tune

Re: 232/236 cam in a ZO6...advice Thanks man,I really appreciate the explanation.
I'm setting up a 239/251, 0.570", on a 106 in my LS6. GMPP LS6 heads milled.055'. Pistons are cut 0.080"and 0.100". I'm only going to spin it to 6800 max (leave some on the table). I was thinking about 4.10s and you've now confirmed my logic.
Z06 has 2.97 1st gear so 12.12 final with 4.10s. Non-Z06vette has 2.66 1st*4.56 = 12.13. I guess 4.10 should work out well. I'm relating this to a setup when I was a kid (17 then, 48 now) -> 2.52 1st * 5.13 = 12.93. Thanks again!!!
