What says my peers??? Is it possible?? How many cid and or rpm you think it would take with a 380cfm head?? No corn,..93 octane to cruise around and be able to lean on it a little would of course supplement it with some race gas for the track Induction will be a tunnel ram so no restrictions there
I think its possible, we recently did 3 482's with a very mild street hyd. roller and heads that flowed 330cfm with 10.8 compression. Single 950 holley on a single plane intake. Made 635 hp at 5800 rpm. With a little more cam, 11.3 compression and a tunnel spinning to 6500 rpm, you'd be close.
Mine ran 875hp on pump gas with only 27' total timing where it began to rattle a bit. Back it off to 25' total when driving. 13.5:1, 6300rpm, 555cui and 387cfm heads
Let me clarify,...iron block without spinning it to the moon 482 max cid,...maybe even less as I'm not sure how much you weaken the crank grinding that much material off
I think you could do it based on what we accomplished, a 482 crank would be ok, 494 may be pushing it. I've run a 494 in Scat for years though, 725 hp but keeping rpm at 6300. I'd do a 482 ,girdled,partial fill, light weight components,internal balance and rpm max at 6600rpm, with the tunnel ram and 380 cfm heads, 11.3 compression.Hyd. roller cam,about 250/260 at .050 on a 112 c/l.
With good rods, pistons, and balancing the occasional trip to 7000 or above I wouldn't worry about. I think your goal is probably about as much hp as you could squeeze out a small cube pump gas setup. You could have the head stretch some but that's for sure not a cheap option
I would build about a 550hp deal that would drive cross country and add a plate system. There's a fella down in Florida that's driving the wheels off his Buick this summer and going fast enough to win a few bucks.
As much as I'd love to feel a N20 Buick id hate to have to "rely" on it for the power,.two plates on my intake would look sick tho

Wow that's it, it's a good time but with a lunch that looks like that I would had guess faster our 12:1 464 te2 heads flowing 370/265 @ .600 runs that on no spray, and I think mine can be faster. I would like to get the short times into the low 1.40s.....but its printing tickets now so just letting go for now Never mind the major redlight or break out, we went to a test and tune only got 1 pass, so we did the cheap race, put a number I knew I could cover with ease on it. The guy went red b4 me so I didn't want to sit on the 2 step and used the pass as full time trial.
I'm the guy w the yellow Buick, super mild combo that's damn near daily driven. 455 .030 over, forged speed pro pistons, stock rods, stock crank no girdle etc. Hydraulic flat tappet comp cam, 9.25:1 compression, edelbrock heads with port match, sp 1 intake, 950 quick fuel with a 150 shot (.064 nitrous jet) 3600lb car with a 3.31 gear Best times so far are 1.39 sixty foot, 6.48 1/8 mile, 10.32 1/4 mile on spray. 1.47 60, 7.08 1/8 and 11.34 1/4 mile on motor. On the chassis dyno it made 404 hp, 426 tq.
Thanks for the info, this just totally put a point on how much my short times are messed up. I am getting the same 60ft but low 6.70 in the 1/8th and 10.50s on top end. I dont want to get too far off top, car looks great leaving.
Me too last week (horrible air) I was running 10.50s with only a 1.48 60ft. I deliberately put a tight converter in it 20yrs ago when most tracks were sketchy as far as traction on a week to week basis unless prepped for a national event. These days most tracks have it figured out and can make traction even on very hot days.
I'm more impressed with the NA performance than the N20 performance,...that dyno is very conservative
He works at a speed shop that owns the dyno. They did my Regal and it came out to 472 at the wheels which is about 23% parasitic loss in the drive trane
