Whats your opinion with isky cams? Why does it seem that my 270-280 mega cam ([email protected])is quite a bit less than say comp cam for the same rpm range?
351w
10-1
270-280 isky
69 351 heads ported and 1.94-1.6
c-4 w/3800
4.56/28" hoosier
current best 11.85 @ 111

Would increasing compression to 11.5-1 and upping the cam to (any reccomendations on a solid) allow me to run 11.40's or so?

any advice appreciated
Mark

Welcome to M&M
In a word, Isky is great quality but OTS.
OTS = O-ld T-ired S-h*t.
No new technology since the 70's.
Same old egg shapped lobe designs they developed in the 60's.
Great for street rods or show queens.

I had a custom Isky - Mega 270 intake, Mega 280 exhaust for my Cleveland.
It self destructed due to (according to my machinist) too little lobe bevel which did not rotate the lifters enough, wiped several lobes. Debris then scratched the bores and bearings.
Everybody seems to like Comp.

Steve Grossen had a lot of trouble with Comp. He kept eating distributor and cam gears on his 351W with a Comp 280H. Comp replaced the cam several times before bothering to check the cam gears. Seems they had a batch of cores with improperly machined gears. I had a similar problem with a Lunati, another friend had some problems with Crower etc. It probably gets back to the fact that there are only a handful of people that make the cam cores and the fact that the cam companies only do statistical sampling. The worst part of dealing with cam companies are the tech lines. Call them three different times and get three completely different answers.

The last thing I heard from Isky was the first article about a Chevy Stroker 305 I read when I was 17.

Car Craft used a custom grind from Isky and seemed to recommend them for customs.

Their 'Mega' lineup came out in the late 80's I believe. It's a more modern lineup... even though they are hydraulic. They came out around the same time (or slightly later than) the Comp Magnum line.

Joe Sherman seems to like Isky.

Personally, I've never used one.

Good Luck!
