Looking for some suggestions from folks smarter than myself (which includes pretty much everyone, yuk yuk).
We are hopefully going to get a 400 under the hood this year. Pure stock '84 Monte Carlo, dirt.
A little more info -- I am planning to run 6.42 final this year (1.88 in 2nd of a 4-spd Muncie, and 3.42 R/P). At 6.42, I think I want to go to 255/60/15 in the back (maybe 245/60/15 LR if needed). I don't know the math but I'm guesstimating we shouldn't be too much above 6000 that way, on a semi-banked 3/8ths which is more often rutty than tacky. Occasionally it's smooth and slick ...
Anyway, we got a 400 donated from a fella who deals in older GM stuff. Tore it down and it is in very good condition. (Code on it is "CTY"; one of the old manuals we have shows this out of a 1970 Nova, having been hooked up to a Hydramatic and s'posed to have put out 375 HP stock).
The block is good, short of boiling/cleaning & honing. The pistons look good. The crank was run out on #3 (getting welded & machined to re-use) but otherwise good.
We're wondering about some ideas on heads & cam, to get us some decent low-end power while not going nuts on compression. One of our friends preaches the bible of Vortec as per the heads. I wonder what size the most common were (64cc?) ... and what kind of compression (ball-park) we'd be getting w/the stock setup on this 400. Also, we have the stock cam out of the block but if we can get some better low-end oomph without risking the hook from Mr. Vacuum Gauge Checker with an aftermarket Comp product or something, I'm all for it.
We run at a few different tracks -- one of 'em is a "pay us $25 at the gate and you're legal" kind of place.
But the other (a very nice 1/4-mile high-banked) checks and enforces a little more -- we're wanting to be legal for there. Have to register 12# vacuum, OEM intake/heads, Q-jet or other stock 2 or 4 barrel, etc.
Any ideas, suggestions, insults, accusations of being miserly, etc., are very welcome.
