Has anybody got the timing figures for this camshaft?
i am building a 351c,2v CC heads and I am looking for a small solid to run in it.
Trying to compare the cls138 to the Crane F238 and a Lunati 411a1LUN.Also looked at the smallest Crow solid but not sure.
Anyone got any other suggestions for a camshaft?
comp just over 10:1
Dual plane manifold - 750VS
mild head work
extractors
max rpm around 6500
would like to run a converter around 3000rpm.
3.25 or 3.5 gears.
thanks

The Crow 21626 solid 238/248 @ 0.050 cheaper with earlier IVC for higher DCR

Thanks northiam,i did quite like the look of that cam.Are you happy with the performance of yours?What size conveter are you running?

3300 stall, 3.5 gears. runs 12.9 ET with no traction! good tyres I guess mid 12's.

mate,you got to be happy with that!Top effort with that size cam. I wasn't even looking to go that fast.I would be happy with mid 13's.
Does it still have reasonable manners?
how did it go when you had the performer on it?

Picked up 20hp changing to funnelweb from performer but I never run the 1/4 with performer. Lost a little bottom end with the funnelweb thou, but got it back with the 750DP.
Daily driver for sure if you like 250/300k to a tank!

ouch.Well I suppose all that power don't come cheap.thanks for the info.
So far it looks like the 238 crow seems to be a good option.
Does anybody else have any smallish solid cams that work they would like to share?
