I am surprised you didn't machine the cap and shorten the main stud rather than use a bolt. Nice looking build, will be interesting to see the various results 
After considering all directions, the determination was that there was not alot of stress on the back cap, unlike a chev, with the thrust , oil pump, rear seal & bearing back there...lol.
There are proven packages making almost double with the stock bolt back there, so I was completely comfortable with it.

ok - time for the recap get 5 gallons of Sunoco Ultra 93 and headed over to make some pulls We bolted the engine up the day before so we were ready to make some pulls when we got there. It fired right off - good sign! Made the first pull after a warmup, set timing, and check for leaks. No oil or water leaks were a damn good sign of things when we were warming it up. 1st pull was mild as we were seating the rings, as well as making sure the Holley Ultra HP 750 was jetted close. With everything good to go the hammer went down - we made the pulls from 3000 to 5600 as it started dropping off after that. What we wound up with was: 511.7 hp @ 5400 & 566 ft/lbs @ 4200 Flat torque curve does not describe this motor - there was 519 ft/lbs @ 3000 and stayed over 500 ft / lbs until 5400 That's averaging 515 ft/lbs for the entire run! We changed the carb to an 830 & got within 1 hp of the 750 - seems to me the carb is not limiting the engine at this point. I was surprised that a stock casting eddy head could pull that much power, I was expecting under 500 for sure. I'm kinda glad things were uneventful in terms of problems, it was just an easy Sunday afternoon!

1 5/8 hooker comps were on there for testing - I didnt want to waste any time with a larger tube and a stock head.
I tried a few spacers, but it really didnt change much - I tried a couple 1" but with similar results.
I really thought one carb setup would walk away from the other but it really didnt...
Granted thats alot of cubes for a set of stock heads
but I wonder if your choke was the 1 5/8 headers...
hard to say... if you cant get it out you cant get
it in... nice torque out of it

Very good point. The next test should shine some light on that as I have a set of ported heads & a victor 340 with the same cam & headers.

hard to say..
I'd think even with untouched Edelbrocks that 1 5/8" headers, no matter who makes them, would kill any performance stroker. If it was a truck motor they'd probably be fine.

I did the same thing. It's really no problem.

I do the Bolt in #5 too Nice build, a set of Shady Dell stage 2 Eddies would work Perfectly with that cam, Mine is 266/269 @.050 but similar .585/570 Lift. With a roller cam they would probably net you close to +50hp with no downside. Not sure if the OOTB RPM intake would flow quite enough up high on that big a motor without some work though (I run a ported Vic 340), but your peak power would probably raise another 400-500RPM. BTW...I'm also running a way too small 1 5/8" x 3" header but that's because I'm not sure a 1 7/8" x 3 1/2 (the size I run on my 427" SBF) would fit the chassis, bang for the buck the cheapies do just fine Stock Small block Edelbrocks LIFT-----IN/EX .200”--131.1/107.0 .300”--182.9/151.8 .400”--216.6/181.2 .450”--227.7/182.9 .500”--235.9/185.6 .550”--238.7/185.6 .600”--242.2/185.6 .650”--243.2/185.6 .700”--243.2/185.6 SDSS ported Flow #'s Gain LIFT--IN/EX .200"--146.9/110.8 15.8 3.8 .300"--196.3/150.1 13.4 -1.7 .400"--245.8/180.2 29.2 -1 .450"--259.0/193.8 31.3 9.9 .500"--268.6/203.4 32.7 17.8 .550"--271.8/212.9 33.1 27.3 .600"--276.6/218.6 34.4 33 .650"--283.5/221.6 40.3 36 .700"--286.6/223.8 43.4 38.2

Been waiting for your reply Wize - I've got a stock victor 340 as well as Ryan's heads ready to make some pulls with this cam - and it is a solid roller. As far as the intake goes - I was real impressed with the results from it - tons of torque and it made over 500 hp - i honestly was expecting a 450 horse motor with the intake / head / header setup I was running.
