For heads, I am using regular low-roser 390/428 heads. Only thing special is I had thick-walled bronze valve guides isntalled and hardened valve seats. As for the cam, it is a Crane 344361 and the specs are at:
http://www.cranecams.com/?show=browseParts&action=partSpec&partNumber=344361&lvl=2&prt=5
Also used Crane parts as follows:
Lifters - 99256-16
Springs - 998393-16
Pushrods - 34642-16
Rocker Arms - 34772-16
Valve Spring Retainers - 99954-16
Valve Spring Locks - 99098-1
I was unsure of which of two cams I wanted, so called the Crane Tech Line. They did a computer profile on my engine and came up with 480 est HP. They suggested their next cam up, which would have put out 540 est HP. They admitted a bad idle with it, so I opted for the 480 HP unit. Now I doubt I get that. A tad optomistic, plus it assumes an engine perfectly tuned, which is difficult to achieve. I suspect about 425 HP as basically I reproduced a 428 PI engine. Hope all this helps. |
