I was looking for something that could deliver decent gas mileage, low weight, high horsepower. Obviously, you make trades, but I was looking for the best I could get. So, without further ado... the 352 de-stroker (also a 348 if you don't bore .30 over). Uses a 327 crank with a 3.25" stroke in an SBC 400, bored .30 over (4.155). For the main journals to avoid heat issues, thick-wall bearings over bearing spacers. It uses ARP 6.202" Ford 300 cid L6 rods (forged, of course) and adapted low compression height pistons to meet the total deck height. 56 cc heads with 2.02 valves and headers, and the rest has yet to be decided. Hot Rod magazine did a special article on it, no worries, didn't buy it whole, they have a free team of experts who can supertune and tweak for quick delivery without lasting performance. http://www.purplesagetradingpost.com/sumner/techinfo/350 chevy engine.html Now come all my lovely questions. Spark plugs... I like non-gapping, non-fouling E3's, use them on my Camaro right now. I've also heard good things about Iridium, especially with SBC and high performance. That kind of segues into my question about heat. How tough would this motor be to cool? They claimed 11 to 1 compression, so I bet the local machine shop could make at least 10.5, and I would be running 92, not 87. More advance, quicker delivery of HP, IMHO. Lastly, camshaft. I was thinking on the low end of a moderate cam, just not mild like they installed. Does this really sound like a good setup for a 500+ HP motor? What are your suggestions for lift/duration, what type of goodies, roller rockers, hydraulic lifters, solid lifters? Lastly, intakes... wide bore, short stroke, big valves (I'd also polish and port the heads further, most likely), tons of flow already. What would help the most? Blower, supercharger (prefer it over a turbo, to be honest), just a cowl hood, what are your opinions?
