DAMN.. don't give up now!! gotta hit 700!! That was the hope but the cubic dollars add up and my guess is that it would mean a cam change to get there. 47 pulls on the dyno probably cost him a small fortune. Hopefully it is close enough for him to run in the 9's which was the original goal anyway.

117. PureStockish360. for my SC/360. K1 Connecting Rods. +.030" Wiseco flat top Pistons 8.6cc. Ported and polished 91C Heads 60cc. Compression ratio = 9.90:1 Cam = Baby Summit retarded 4 degrees per n2oJoe. Sealed Power Hi-Rev Hydraulic Lifters HT2011R Harland Sharp Roller Rockers 1.6 ratio. Carb = n20Joe 605 Motocraft or NEJoe 750 Carter AFB. Ported Free Flow Exhaust manifolds The dark lines are the 750 AFB worked over by NEJoe and the light lines are the Motocraft worked over by n2ojoe. I am a very happy camper! PS360Dyno by Rick Jones, on Flickr Click on it to hear it run. PureStock360 by Rick Jones, on Flickr Thanks again to Joe and Joe for working over the carbs and of course thanks to Bob for the pizza! I always find it interesting to compare the results to what was published back in the day. According to the Specs the 1970 360 4bbl engine put out 290HP and 395#/ft of torque. They must have rounded up... alot!

Nice to see the bigger carb did better, as many elsewhere claim they don't.

Tell you what though, n2ojoe has got his shit together on the Motocraft. Both carbs had to go bigger in jetting to handle the thirst of the 360.

They must have rounded up... alot! Like that stockish 440 build I shared. Just a hair over 400 in TQ. No Factory Big Block ever made 500 ft lbs, 450 tops. Either that or you need to use their Dyno. I also bet this 365 horse motor pulls harder than a lot of 525 horse combos we see.
