I like a long rod, so my combo's a bit different from the usual "stroker kit" combos. I have a 400 block bored to 4.402", a 4.250" stroke, Icon pistons with a 1.122" compression height and a 6.700" rod yielding 517 cubes. That combo puts the pistons down in the hole .033", so the block was then decked to zero. Most 512 kits use a 1.320" compression height with a 6.535" rod which gives you zero deck already, but I like the long rod. There's more than one way to skin a cat after all!Would like to read about members builds. What combination of parts are you running? And if you had do it over again what would you change? Opinions on cubic inchs too.
Sounds like these low deck strokers are the way to go to achieve 600hp+ on pump gas and still be reliable.1) 451, 950 Quick Fuel, MP single plane, ported 452 iron heads, Comp cams solid roller XR292R, Ross pistons, 9.5:1 compression, Scat H-beam rods, 440 factory forged steel crank cut to 400 mains, HV oil pump, 3/8 pick-up, MP windage tray, stock 4 qt oil pan........588 lb-ft @ 4,600 rpm and 621 hp @ 6,100 rpm.

2) 451, 850 cfm Mighty Demon, 383 single plane Victor intake, ported 906 iron heads, Racer Brown solid roller CCR-78/80, Ross pistons, 9.8:1 compression, Scat H-beam rods, 440 factory forged steel crank cut to 400 main size, HV oil pump 3/8 pick-up, MP windage tray, stock 4 qt oil pan..........555 lb-ft @ 5,800 rpm and 676 hp @ 6,800 rpm. August 4, 2007.
Both fun on the street, but not efficient with 4.89 gears and a 4-spd manual. Both had the '71 Road Runner sideways a lot.

You would be surprised at how much I`ve changed a team G , the huge plenum is good for big engines, if u can get the runner flow close to equalized. Made a bunch of diff. but still messing w/ it. My air flow meter went down and haven`t replaced it yet.Wow, gotta say those are impressive numbers for a low comp motor with a small roller XR292R especially as the ivc on that is at 72 deg. making your CP somewhat low and with only .588"..... I built a 440SP motor back in the day in a similar vein with an 850DP (inferior), Team G int. (crap), 906 bv heads probably not much more than 260cfm (inferior), Comp Cams SFT .650/.650 290@.050, factory bottom end, approx 9.8:1 CR, HV pump external oiling and could only manage 490hp worked out on weight/mph, I was on the right path though I think?...the weight of those rods/pistons in an SP motor is enough to kill the hp....1100/900gms per hole if I remember correct.
That combination isn`t supposed to work well on anything , so I`ve read. The other way, w/ a reg. 4 barrel intake w/ a dominator spacer on top, is what I`ve read is the hot ticket. I don`t have room for even a victor w/ my filter. Think I might have the team G professionally flowed when I get done w/ it, 2 more tricks to go first.My t-G was a Dom flange with a 2" adapt open spacer for the 850 for even more plenum, motor ran really well, I hit 7300rpm in the traps a few times but the hp didn't seem to be there with that set up.
