Update ish.. email@example.com @ 7,859ft DA...still all steel minus back seat.
What top end stuff did you break??
Few things... But the one that really pissed me off was the helicoils for the rocker shafts were pulled out and Bam. Not gonna use bolts again. lol
What was your assessment? Soft aluminum, poor threading and helicoiling? Not enough bolt thread engagement?
I'm guessing poor threading and helicoil.. I threw the heads in a box, i'll trya nd fix them later, maybe i'll get lucky and use them on another engine.
What were the springs, cam lift and rocker ratio specs you were running? Thanks
Howards solid roller, .640/.645 1.5 rockers.. can't remember the springs, but they were even on the light side for a solid roller cam.
73 Duster , former drag car, converted back to a street car, front seats only. 3240 pounds with me and a full tank of E85. Stock bottom end 318 Magnum, 150k not rebuilt, $150 Craigslist shortblock.

11.48 pass on 15 psi.
I do have to make a correction, right now I have the PTC converter in, during these passes there was what I think is a 4500 stall j converter. I sort of blow thru it in the video, hopefully it won’t be as bad and I make a 10 second pass with the Craigslist engine. Eventually I will build a better engine (goal is a low low 10 second car in hot weather) with forged pistons, better rods and a forged stock stroke crank.
What size turbo?
69mm compressor, 83mm turbine I believe, $200 China turbo.

What did you have for cylinder heads and any work to them?
If you get any parts wrapped in bubble wrap, don't pop it! You don't know what might be in it...
I updated the engine specs.... and the rods were in plastic bags...have had them over 5 yrs now...
I haven't been on in a long time....69 swinger ...factory 340 4sp....well that was many years ago...lol... 340 with: 318 dump truck crank...JE pistons 11:1..factory rods... .20 over...roller comp cam .605 lift..crower lifters.

At Rockingham Dragway (elev 426’) multiple December 2019 55 degree weather runs in 11.75-11.82 @ 110-112 range, weight at that time with driver was 3570lbs give or take. July 25,2020 run in sweltering 90 degree heat, same setup but with van weight reduction of 200 lbs (now 3370 lbs w/ driver, 3150 lbs van only) and addition of double adjustable QA1’s front/rear, only run I got in was a 11.98 @ 109+ Was setup for a better run in the slightly cooler evening but had line lock brake drag issue and ended up running a throwaway run. Will be shooting for runs in similar cooler weather come fall for a better apples to apples comparison (from the 200 lb weight reduction as well as learning the shocks) So high 11’s now, with weight loss, shocks and better temps I’m hoping for something in 11.6@113 range maybe better
I was hoping i would of got to add my build to the small block 10 second post. But for now I will have to post here.
