528 CID Looks like it made about 872hp at 7100 rpm Indy 440-1 heads 13.6 CR 0.800" lift intake valve
Do you have any more specs? 4.500" bore? Cam duration, LSA Bore 4.500 rings . 9mm. No vacuum pump. C12fuel. Harland Sharp 1.6 rockers, 3/8 smith pusheods. Cam is over 280 on the intake, Tim was going to call me with full specs. Originally a Godwin spec'd design for 440-1 heads on a 497 i believe.

I have no idea what my 528 with -1s makes on the Dyno, but I know it runs really in my car and I love the combo. My car weighs 2825 race ready last year. I added some tubing to the car over the winter so I don’t know how much weight I added but probably 10 lbs or so. I just ran my fastest pass last weekend. 5.48 at 124mph. That was spinning. The following pass was an elimination pass, car hooked up great but I had to lift due to being ahead. Incrementals show I was on a 5.44-5.45 pass. Engine built by Tim Bowman at Bowman Performance. What transmission and rear gears are you using?

For my combo, 4.56 and a 33 inch tall tire worked, went through at 7400. If you race only 1/8 mile, AND run a powerglide, you can go higher ratio, but i wouldn't recomend it with a 2.45 low torqueflite.

528 CID Looks like it made about 872hp at 7100 rpm, 723 ft-lbs at 5600 rpm Indy 440-1 heads 13.6 CR 0.800" lift intake valve
Do you have any more specs? 4.500" bore? Cam duration, LSA Jim, cam is a 1625b/ 1634b, .501 int lobe, .500 ex lobe? Duration 283/286/110+4 for a 106 install. 64.5 degrees overlap with a lash setting of . 026, which IMHO must reduce the actrual running duration a bit comparead to more modern low lash designs? With the shorter exhaust duration, i wonder if that is better with 13.6 compression, versus say 15/1? With that early install, it pulled very well all the way to 7200 rpm. Never pulled it higher. One more note, that 1625b intake is a radical lobe, as i had a cam ground with it way back in 2005 and was told it was used in superstock motors then.

I just assume this is a repost of one of the more recent 440-1 builds? Either way #'s look good to me NICE BUILD! a friend of mines engine. New iron block, 4.15 x 4.500 528 cubes. c14+. The heads were done by R&R, cam was designed by Todd Goodwin years ago.

If you race only 1/8 mile, AND run a powerglide, you can go higher ratio, but i wouldn't recomend it with a 2.45 low torqueflite. I run 88s in my car with a glide. I run a tall Phoenix PH338 that is 107 roll out. Shift at 6900 and cross the 1/8 around 72-7300. She would be singing at the 1/4 mile mark I bet.
