Little update, nothing really substantial.
I've decided to take the HO engine I have and build that. It's been hard for me to make time to get to the JY, so I'll make do with what I have until it comes time to get the front accessories, and I'll get the explorer stuff then.
After much deliberation, I've decided to send the HO intake to T-Moss and work his end (yes I understand all the aspects of the situation, and it's literally the most economical way to get where I want to be with this engine, I've been stirring on it for a couple weeks)...
I flow tested my GT40 heads I ported over a decade ago, and am very happy with what I got out of them... No flow bench then, just a kid in the garage grinding away with the best info available.
Intake:
.100- 55cfm
.200- 130cfm
.300- 184cfm
.400- 208cfm
.500- 218cfm
.600- 218cfm
Exhaust:
.100- 35cfm
.200- 102cfm
.300- 145cfm
.400- 171cfm
.500- 188cfm
.550- 189cfm (coil bind on the test spring)
I have a couple of IDI's to finish up before I can do the machine work on this thing, but as soon as I am done with those, I'll drop some pics of the 302 up on the machines, and all the other details.
