biggest cam without flycut

[GMMAD]

I have a LS1 with a 222/224 cam and 241 cast ported heads milled 30 thou to 11:1
and I am wanting to put a bigger cam in
was hoping something mid to high 230's
any one know how big you can go without fly cutting the pistons

[Marc 85Z28]

You say the heads have been ported, so they have larger valves, correct? Stock heads milled .030" with 2.02/1.60 valves and even a stock thickness head gasket won't accept anything much larger than what you have now. Mid-upper 230 duration, no way. 228-230 maximum, and even then you should measure.

get a custom cam from some one who specs cams.or go to the TSP website and ask them what mite fit.

Why do you need the biggest cam you can fit?

i wanted to fit a texas speed magic stick 4
but i dont think it would fit so just wanted to know how big i can go
plus they dont answer my emails

[Mr. Luos]

With the heads milled I wouldn't go MS4 either.

Custom cam is what you are looking for.
You likely don't need the biggest cam you can fit either to meet your goals.

texas speed havent answered any of my emails
what are some good US based shops that would freight to aus
Ive bought stuff through speed inc before might try them

[Mr. Luos]

Speed Inc. is great.
Not sure which shops will ship to you though.


Why do you think you need the biggest cam that will fit?

i dont want the biggest that would fit
but i want something around mid 230's
quicker 1/4's and that that sound that only a big cam can give

[Mr. Luos]

Head gasket thickness?
Otherwise stock bottom end LS1 correct?

This would likely fit your needs well. I don't like to run any cam without measuring (using clay to determine clearance) first.

yep stock bottom end
stock mls head gaskets

yeah I know the 232/234 would fit
but its a bit of a dinosaur
theres better cam around
I just put the heads on a few months ago so i dont want to have to pull them off again to fly cut the pistons

your probably better off calling TSP rather then emailing them, they seem to always be pretty busy and were slow answering my emails also.
