I think a 268 high energy cam from comp cams would be good.

dan42 · 10-22-2008, 10:36 PM

Lots of threads on cams - do a search, you should find more than you need. Sounds like a great motor.

drewdude92 · 10-23-2008, 01:42 PM

alright thanks im pretty sure that would void the warranty with me doing this? ill read on the warranty some more i guess

PanelDeland · 10-23-2008, 03:57 PM

Call a cam company.They will ask about a thousand questions but they will also set you up with a cam that works for your,vehicle,driving style,gearing,tranny and any other thing you can think of.This is what they do for a living and it's free.

drewdude92 · 10-23-2008, 07:06 PM

a cam company sounds like a good deal? where in the world would i find that number?

cdowns · 10-23-2008, 07:13 PM

google

t&tkennels · 10-23-2008, 09:01 PM

on comp cams website , theirs a section on there where you can type in all the specs on your truck , & they will email you back with a cam suggestion.

drewdude92 · 10-23-2008, 11:30 PM

I'm going to say that you definitely will void the warranty. Also, if you plan on doing it yourself I think there is something about a qualified mechanic installing it for the warranty to be in effect anyway.

drewdude92 · 10-24-2008, 06:38 PM

hmm i think ive pretty much decided that ima just rebuild an old block i got sitting around i want around 300 hp with a pretty sweet cam in it i just like the sound of it. Any good kits combos you all would recomend?

Gray Ghost · 10-25-2008, 05:44 AM

Best idea yet...I'm not a fan of GM crate motors. The 268 cam is OK but if you want a thumpy idle you'll want to look further up the list.

Edelbrock has some good top end kits that make a rebuild easy. Call them and tell them what you have now and what you want...they can help with the cam, heads, intake, carb, EFi, etc.

**truckdude239** · 10-25-2008, 07:21 AM

got all my kits at www.northernautoparts.com

drewdude92 · 10-25-2008, 09:13 PM

yup im still lookin around ill prob have to tear into my motor a lil more before i give them a call to tell them what i have?

Gray Ghost · 10-25-2008, 09:30 PM

Not really....give them the block casting number [driver's side near the firewall behind the valve cover]
and tell them what you will be doing the most with your truck. They will ask what transmission and rear axle ratio you have and maybe another question or two, then they should be able to give you an answer.

drewdude92 · 10-25-2008, 09:35 PM

alright hmm wish me luck gettin to that darn number...i think i can do it with a mirror though i know what tranny im have but rear end ratio i have no idea im pretty sure its the original but dont know any way to find out?

Gray Ghost · 10-25-2008, 09:39 PM

I hear ya...that one is a hard one to get to but with a very bright light it's not too bad.

Alternate plan....go 60mph and record your rpms. Then measure your rear tire height at the tread there's an online calculator [don't have the link but I'll bet someone does] that figures axle ratios for you given the above info.

drewdude92 · 10-25-2008, 10:01 PM

hmm sounds easier than it is because my speedo is way off? lol ill have someone set cruise at sixty in front of me i guess and i measure the tread to the brim of my rim?

Gray Ghost · 10-25-2008, 10:49 PM

You measure the tire's height....from the pavement to the topmost tread in the wheelwell. Probably 27" or more up to about 30" tall.

drewdude92 · 10-25-2008, 11:19 PM

o der der der lol ill do that tomorrow
