hi all, I had cam ground up for my 243 headed 6.0 ltr.
I didn't give a power goal, but emphasised how I need low end grunt- around 3000 rpm, then the rest of the race the rpm would sit around 5-6500 rpm.
This is a marine application and this is the cam I was sent-
.050- 208, 210
.006- 259, 262
lift- .537, .510
centers- 107, 111
lobe sep- 109.
I was told this be VERY square on HP and torque figures. I'm scared it won't make 500hp and this boat hull needs at least 500 for it not to be a pig around bends.
Heads flow a very stable 290 cfm, pump fuel and vic Snr.
I'll be devastated if it wasn't worth 500hp!
maybe it's my fault, but this a well known shop and I said it was a race engine. I would've thought that a 6.0 LS with 11:1 and nicely ported 243's would smash 500 without really trying?
