Hello-
I am new on this forum, but am a regular on the sweptline.org forum. I'm collecting parts for a 225 /6 build, but am in college, so the collection is slow. The engine will be in my '64 D100.

Here's what I have so far, as well as the plans for the rest of the build: engine is a RGFC (high deck cast iron, forged crank). I have 340 high performance springs; they are "dual" springs with the inner dampner. My new valves should get here soon, the are 1.70" intake, 1.44" exhaust. The head has already been milled .100" and is mildly ported, but that mild will soon turn to wild! I'm planning on using one of the cams listed below. I'll have ARP rod bolts and main studs. Also, I have not decided upon the intake/carb set yet. I have the Super Six intake and carb on right now, but would like to put an Edelbrock 500 and Clifford's Ram 4 bbl manifold on.

What header(s) have you guys found to be the best one (that fits my truck)?

Which of these cams would yield a higher hp and torque level: a 268 duration, .447" lift (Clifford) or a 264 duration, .448" lift (Isky) cam? How big would the power difference be between these two cams? Trying to decide between a $220 Clifford cam or a $155 Isky cam.

I think the guy at Clifford, however nice and knowledgeable and nice he may be, is a little on the bias side about when I ask him questions about his parts vs. other brand parts (cam, headers, etc.)

Another question for you high performance guys: Suppose I had either one of the above cams in my slant six, what differences would there be running an Edelbrock 500 and a Super Six intake? I think the Eddy 500 is about the right (or so I have read) for my build and I was wondering what effects would come if I were to stick with the 2 bbl. Would this completely starve the engine and make it run like crap? Would I just have less power and slightly better mpg? Any help would be appreciated as I would like to stick with the carb and intake I have right now, but still build the rest of the motor the same and later on when I get the $150-250 for the carb and $300 for the manifold, I can just put them on.

Also, what do you guys think about roller lifters (not roller rockers), windage trays, and crank scrapers? Are they worh it on a non drag race motor?

Thanks in advance,
Stephan
