My 455 was basically copied from a 455 engine that Cliff Ruggles built which made 455.4 HP and 522 ft lbs torque on a dyno. I rode in Cliff's Ventura right after he completed his engine when he still lived in Pgh and was totally impressed. (I believe that was in 2003) My engine seems just as strong even though I have never run my car at the track. The weak link of my car is the 8.2 rearend which I may upgrade someday. If I had sticky tires I think that I would break stuff.

Dave's 67 GTO
My car is finally on the road after a 5 year ground up restification. The engine was build for torq. I patterned it after an engine from Butler Performance.
69 400 Block Eagle stroker kit from Summit. (H-beam 6.8 Chevy BB Rods. Chevy SB 400 pistons) 4.165X4.25 Elelbrock Performer 87cc Heads. Dougs Headers Comp Extreme Energy 268. Harland Sharp 1.7 Roller Rockers. Edelbrock Torquer EFI intake Edelbrock 1000CFM Throttle body Mass-Flo Wiring harness Ford A9L Computer Ford Lightning 90mm MAF Home build distributor using a Pontiac points distributor and Ford TFI internals. Rick's EFI fuel Tank. Diablo Chip 3.55 posi w/Kessle 600 .64 OD 5 speed. Dyno first tune produced 370Hp and 430Tq at the back tires. Please note that the value covers have been replaced with a nicer ribbed set. I'll post a copy of the dyno sheet once I get my scanner fixed. Dave In Idaho

Dave's 67 GTO
Finally got the scanner fixed and the file down to a managable size. I'm more than pleased with the results of my effort to build a stout street motor. We should be able to get close to the 400hp level with the next tune. The plan is to drive it to now and after 500 to 600 mile retune. Try a little leaner around 13 to 1 and a degree or more of timing.

Thanks to Wayne at Schicantek Performance in Milwaukee for machine work, assembly, and useful advise. Thanks to Cliff Ruggles for the build advise, and giving me the confidence to pursue this type of build as my first rebuilt (top to bottom) engine. This whole project revolves around the 670 heads I purchased at Pontiac Heaven in 2006 (if I remember correctly). They were heavily ported, new valves, springs, guides, etc......ready to bolt on and go......for $300!
I programmed and milled the chambers to unshroud the valve and add the scallop thus increasing the chamber size from 72 cc to 80/81 cc. So I'm running around 11.1 compression............on 92/93 pump gas! Idles with 11/12" of vacuum......I checked all summer since the initial start up for any detonation. Only ran into it once when I got some bad gas from a lower end gas station. Just sticking to the tier 1 stations now. I just found out on Tuesday that I've been running way more timing than was needed. So I even have more of a cushion now! Was at 34 deg total. Took it to the track and found out it loves 26-28! Never had a hint of detonation on the plugs. 1971 455 2 bolt +.030 KB forged flat tops, Mahle rings -removed sharp edges on pistons, head chambers and polished both to help eliminate detonation PPR ultra light I beams main studs, 3/4 windage tray, "N" crank, radiused, bull nosed, (5# lighter than stock) neutral ballanced, PRW ballancer, TCI flexplate Crower 60245 hydraulic flat cam 248/253 @ .050 112 lobe sep. cam advanced 2 deg. for heavy car (106 CL) standard Rhodes lifters 1.52 PRW stainless roller rockers Tomahawk HEI dizzy, Taylor spiro-pro wires RPM -gasket matched, separated H20 X-over 800 cfm Q-jet, (recipe #3) 1 3/4 Doug's headers, Pypes 3" w/ X 1970 3.55 12 bolt, Summit cover with cap locks Strange tapered "C" clip eliminators with axles Quarter Master drive shaft, loop Mad Bomber T400 H.D. trans PTC 10" nitrus converter, 3000 stall So far, with a 4400 pound long roof, best time is 12.655 @ 107.1. That's with a hesitation at the line from the carb. I just wanted to give the info on my build to show that if you are careful, you can run higher compression with iron heads.

Runs cool with AC on and has good oil pressure. has a little lope to the idle, but also returns about 17 mpg on the highway (Also has a 2004r with billet parts in it that helps with the highway rpms) (3.42 gear) this combo helps maintain a "stock" underhood appearance as well. Can also run any gas from the pump I like in it.
