This is the engine that was reported on in 2015 by SC397 and Stickshifter. It has been installed in a ’69 Rambler, finally done in May. The engine is home-built, 426 CID with ported Edelbrock heads, 12.8:1 CR, Torker, HP 1000 Ultra, and a small solid roller. The crank is ground to 3.850 stroke x 1.900 wide, with 2.0 inch pins. Rods are offset Callies for SBC, 6.0-inch. The valves are 2.100/1.625, and the heads flowed 289/227 cfm at .600. Dyno’d at 642 HP at 6400 and 590 LB-FT on E85. A different cam and step headers were installed before the build was finished. The car is complete, with stock full interior and exhaust to the bumper; weight with driver is 3110#. 904 trans, tight 8” converter, 3.73:1, P275/60 drag radials, stock suspension with slapper bars and adjustable shocks. Four trips to the track so far, generally runs mid 9.7’s at 135-136. Best is 9.70 at 134.9 with 1.34 60’. Mild foot-brake, shift at 6700, ET at 6800. The car is driven frequently, more than 700 miles this summer. As an aside, it seems fairly insensitive to air quality, averaging 135.5 in good air (600’ DA) and 135.0 in poor (2850’ DA). Will attach photos and time-slips when and if I figure out how to. Edited by ramblermoosecocka - Oct/03/2017 at 8:51am |

Now that is the part I really like. Most think you have to have Cal-Tracs to run 13s, because Slappers don't work at all. lol |

that is really impressive an makes me feel like our car runs like crap, who did the cam for you? our car is 150lbs heavier 427inch adkins ported iron heads flow 303/254 and has a pretty big solid roller in my opinion, 278/288 @ .050 and 740/760 lift with 13.1 compression a 950hp on e85 with a 727 and a 6000 stall 8inch with a 4.56 gear and has been 6.61 in the 1/8th don't have good 1/4mile data but still either the chambers on the edelbrock head makes a big difference or mid lift flow or our cam is crap, not sure but 150 lbs shouldn't be .6 tenths off. any how congrats on a excellent combo.
