20-813-9 - Xtreme Energy™ Retro-Fit Hydraulic Roller Camshafts
If you have aluminum heads and cylinder pressure of 180psi or so, then hang on tight man!
That's actually about 1 cam size bigger than mine, plus it's a roller, so that might fatten it up a bit more. :)
But I tell you what; forget about fuel economy....... :(
Yes, cam it is [email protected] 236/242 and lift of .544/.541 and my heads are 1969 ported X heads .040 over 360 (367) I have 4.11 gear in it right now but will probably go to 3.55 or 3.70. the engine was built buy Performance Machining who does all my engines and has all the goodies in it and I was not looking for fuel economy, just Raw Horse Power!
