I'd rather see someone stroke a Pontiac, then toss it in a scrap pile like the fate of many 350 BOPs. Or even worse, toss it in a scrap pile and build a Chevy!
I say, if he's not happy with it, stoke it like a teenager!
Thanks Mike, I appreciate the links, informative and I like the Tomahawk crankshaft. I was wondering if I would have to cut reliefs in the bores for the larger valve sizes and also unshroud the valves.
Bjorn, even tho its at my expense, laughed pretty good on that one, too funny! Told a couple friends and they chuckled pretty good as well.
The small bore of the 350 often requires relief cuts just to clear the bore, let alone unshroud the valves. This depends on the camshaft, amount of overbore, and valve sizes.
If your 400 heads use the 1.66 valve, this would be less troublesome (of course still check clearance) and still provide good flow with some port work.
Although I am a fan of a stroked 350, it's not nessesary to have a good street engine. Before I'd do that I'd consider boring it .060 over and just adding some KRE 290 cfm heads built with 2.07 intake and 1.66 exhaust valves, machined to 68-70 cc's, zero deck the block and install a good cam, intake and ignition.
.060 over pistons are common and you'll be around 9.75:1 with the aluminum heads, quite a good little 365 cu in street engine you'd have there.
Wanting a Custom fit in an off the rack world.
I don't have time for a job, I just need the money.
Hey Mike/HO428, where are you guys located in SC? I am in Summerville/N Charleston and have parts to sale/trade, send me your phone numbers and lets chat. Dan
