Ok guys, an update to an old thread. I am still deployed, but I'm buying parts for this build for when I return. I've settled on the 383 stroker, but I'm still working out exactly what I'm getting and who I'm getting it from.
I'm either going to buy from ATK Performance or an Ebay builder, 1951herb. I can save money by buying from 1951herb, but the warranty is not as good. But the main question is below.
The question I am asking is about the heads. I don't care necessarily about horsepower or speed. My main concern is torque. Soooo, I would like to know if any of you have a good experience using the swirl port (TBI/193) heads for a build. MANY to MOST people say these heads are junk, but I've also read that these heads are just as good or better than the Vortecs at or below 3000 RPM. That's where I'll spend most of my time and I'm interested to see if these heads will support 400-410 ft/lbs like the builder claims (gross). I am geting rid of the EGR system and going with a dual plane intake, probably an air gap, and I'm going with Sniper EFI for easier tuning. The cam suggested is 210/220 at .050 w/ .500 lift, 114 LSA. He says 350 HP/ 410 TQ with that combo. I don't have enough experience to know if he's right. All this with swirl port heads mind you.
So I'm looking for suggestions. I do know that Vortec heads will be better, and I am leaning that way. I'm just curious to see what can realistically be achieved with swirl ports.
Also, I thought I'd post a couple pics of Hattie as she is today, just cuz I want to.
