No initial start.

Quote from plumbpiper on January 2, 2021, 12:26 pmThat was what made me suspect the lifters. Comp was bleeding fast. Also I should have suspected the fast cranking, but thought a high torque starter might have done this. Kicking myself for being so dumb as to overlook this. I will let you know how this works out after my new lifters get here. Hot Rod magazine has an article stating I could run solids, but lash can be a problem between hot and cold. I opted to get the correct lifters and save the solids for the next build.

Quote from plumbpiper on January 3, 2021, 12:08 amThat's some healthy lift. I installed .565/.565 lift, but went long duration, reverse for turbo. Advertised 292/280. Didn't think I needed massive lift because I am force feeding it.

Quote from bdhulderman on January 3, 2021, 2:03 pmThat's right, you wouldn't need as much lift and duration to get the same flow with forced induction, but that wasn't what I was going for. I wanted to see if I could get 700 Hp N/A on pump gas in a small block, and I did with 700 Hp @ 7200 rpm. Had to go with the high lift and duration adv. 312 and 454 CID for my dart iron eagle small block. Just think how much power I could get with a few pounds of boost!
I used the software I developed that I give away for free to determine what clearances I could get away with before I bought the parts!

Quote from plumbpiper on January 5, 2021, 10:21 amVery cool. If I do another build I plan on an aftermarket 351W block to do a small block 427. Looking for a 67/68 Mercury Comet Cyclone body, or a Torino. Might even be cool putting one in a Rancharo.
The only previous turbo experience I have is with the T-bird 2.3 Turbo coupe. My son and I squeezed just over 275 hp out of one with just a few mods. I knew turbocharging was a very good means of getting power after that. I doesn't surprise me at all that people are getting 600+ hp with those 2.3 motors using forced induction. I thought I was doing well by pushing a 1972 351 Cobra Jet to just north of 500 hp back in the mid 80's. Shoe horned it into a 4-door 1977 Ford Granada. Twin 600 holleys just fit under the hood. Man was that a neat street sleeper.

Quote from Ratchet on September 23, 2022, 1:36 pmGood story,, I definitely learned a little bit here... Since I have no same I'll tell on myself here... I had similar problems,, turns out I had had the distributer 180 degrees out,, sheesh... Bonehead move I know... So the whole time i was reading I was thinking that and I finally got to the point where you figured it out... Probably wouldn't have guessed that so thanks for making a post telling us what you figured out instead of leaving us hanging...
