performance cams

the "search" section is out of order currently so i will ask for everyone's opinion.

well i just got my head set from asian auto parts in the mail yesterday, so i am in the process of finishing up my gti hybrid engine. anyway..before i put everything back together, i was thinking of getting a performance cam (1300 8 valve head) to help my highway driveability. i do NOT want my engine wheez out in the upper rpms. i have 5:12 gears w/31 inch tires so i am geared down so i need my engine still pull hard in the mid to upper rpms. i figure the mid-range regrind cam from asian auto would offer the best performance increase for the money.

what cams are you all running and how do they perform as far as highway driving? please tell me.

Re: performance cams

I use the 330 grind from Isky and dual springs , oversized valves, ect . But , I also have 10.22:1 compression , and can take advantage of the cam's range and lift . This one runs between 2800-7200 rpm ,upper limit is 10,000rpm . Not really good for torque , more suited at high rpm shifts and upper range pull . I'd go ahead and use Dave's midrange grind , I hope you opted for the bigger exhaust valves . If you are getting a cam , it would be a good idea to order an adjustable cam sprocket as well . This way you can dial the cam into what the engine needs .

Re: performance cams

thanks for replying..

i got a "head set" from asian auto..the complete top end gasket and seal kit which also includes valve stem seals. i am redoing the head myself with new stock size valves as i cannot do the modifications my self to the head to fit the larger exhaust valves and i am on the typical shoe string budget. might shave the head 20 thousanths though. the set took roughly 3 weeks to get after it was ordered. not bad.

sarge, so how do you like that top end isky cam? i wonder how that compares to aap's "full race" cam?

Re: performance cams

It's similar to AAP's race cam , but a different lift and duration. The Isky 330 is as far as you can go with lift and duration without having to build a lot of other parts into the engine. I still need to dial mine in better , waiting on a cam sprocket. I love the way the cam helps it breathe, sometimes maybe a little too well . This cam really don't pull all that bad at low rpms, but you can notice a difference . I'd go with Dave's midrange for what you are building , he will tell you the same thing, give him a call .

Re: performance cams

Believe it or not Brent at Trail Tough basically told me a Cam was a waste of time. He said you might gain some during the cams range but you loose alot more in other places. I kinda didn't understand that cause I know alot of people that run cams......
