putting nitro thru a flat head that only has only 3 main caps would be something for sure wound need a big set to sit in back of that thing. or just give up on life and wanted to go out with some flare some of the big blocks i have can take over 1600+ hp easy that would be what i would look at if someone was going to do this .i did look in to this for someone that needed more power never did any thing with it

they used to puts lotsa nitro through 301's in the early days of jr. fuel

Don,,,, where were you 40 years ago,,, we could have used you at the track Peter

Tuffnuff, maybe he means "Good Night"? I wasn't around drag tracks much at all but I enjoyed short circle track racing as a spectator. I know where most of the Deuce coupes went and saw a lot of them running at short tracks and the old Hatfield track near Trenton ran "stock" cars. I recall the 1955 Packards that were allowed to run 400 ci V8s because they were stock in production models, just before the company vanished! Anyway I recall the drag news in Hot Rod magazine from the west coast of hot rod heavan and marveled at the beautiful glass slipper which was one of the early SBC conversions from the initial flathead setup, but that was long ago!

Thanks Don, I'm always interested in reading your posts. I don't fully understand them sometimes, but I sure enjoy trying. I've heard it or read it in the past that somewhere around 350*F, nitromethane undergoes a chemical change that releases the oxygen in it. Can you nail this down for me?

We used to run the biggest fuel pumps that we could get from Hilborn and then Crower---we also ran 100% nitro with super low compression and only around 30% overdrive on the blower whereas most at the time were running 45% or more--we ran 28 degrees timing while the elephant guys ran 75-90

We also started refrigerating our nitro so we could get more thru the system--it changes 2% spec gravity per 10*f and if we could get it down to 30* it would bob out at 110%. To do this on the road we would rent 2 adjoining rooms and ice the nitro down in one bathtub and everybody would use the shower in the other room( tho not at the same time!!!!!)

sounds like a fun time jerry. my dad run a B alter i think they may have got some nitro from ron elis. i was just a kid but they called it helicopter juice ??or windmill juice?? all i know was the hemi lifted the head and dump water under the slicks and the fire truck was running down the track at tri city they came back with a hurt hemi and dad had to put new studs in the deck i still remember trying to help when my dad then he was trying to put the iron main cap girdle on under the T after the hemi lifting the head dad said it never ran the same and said he wish he never used the stuff what ever they put in the tank

Pat

we had good luck with it----but we ran lower static compression and less timing
Most people got in trouble with it because you need lots more fuel to get the mixture right and less timing . Also most gas or alky motors were higher compression and couldn't stand the extra cylinder pressure
We did have a fuel pump go weak on us once and we threw away every thing outta the short block but the studs , nuts and washers

yup i am sure dad was not up to speed on what ever they used the learning cure was $$ more then he could take .i still wish i had all the hemi s and the T

we used to watch both sides of the road as we drove, watching for them 300s setting out behind a barn---when Donovan got his block out it sure was easier

yes we some of them old tanks that dad towed home . i remember kicking holes thru the rusty rockers of the bodys . dad had hemi cranks in the house by the back door dad did think it was a good spot till one fell on moms foot
