It uses the same heads, cam and 565 CFM carb as the early 383 which was unusable until it was defactored to 280 HP. The only advantage the 426 has over the 383 is it can fit a little more duration, with identical cams both engines would make almost identical HP. I did this test in my Sport Fury back in 73 to prove a point to some friends. I had been running a 426 street wedge I built using a 413 .070 block because the original block was cracked. It had a stock 63 Max cam, stock 915 heads a TM7 mani and a 4779 Holley with a stock Road Runner 11" convertor, it typically ran 12.50s with an occasional high 40 at 110-111. I had pulled the engine to upgrade it and still had to race every weekend in the brackets so I took an 80K mile 383 short block that came out of a friends car and put in the same cam, heads and carb with a Torker mani I borrowed. The first day out it ran 12.50s at 110 as it smoked down the track, it also had about a half of a point less compression than the 426, my friends were shocked, I wasn't, I still have all of the time slips dating back to 71.

I'd be ditching the AMX and finding a '71 Opel GT. 20% off 75 HP looks pretty good to me!

Jim Wahl · 12-07-2016, 02:18 AM

My old 1988 Cadillac Cimarron, 2.8 - 125/155. - 20% = 124hp.
Oh yeah! Jim
