I've now pretty much sold off the engine parts of the old 461 bbc combination. The only thing left to sell is two different 8" converters.

Now I'm in the early stages of planning the replacement engine.

Let's say a goal of 9.0's on the heat and 8.80's in good air. At 3400 lbs w/driver, what kind of honest/realistic power is required (flywheel) to run that kind of ET.

I am not too familiar with ET vs MPH at that range, but I'd assume 148 to low 150's?

Car is a small tire/stock suspension deal with a th400. Trans will likely get a 2.10 gear set and the 12 bolt will lose the 4.33 gears in favor of 4.11's along with swapping from 28" to 30" tires.

horsepower

I have an engine customer with 1075 HP BB Chevy. at 3500 lbs, his best so far has been 9.01 at 152.25. This is with a Jerrico 4 speed ( 3.0 MPH faster than an auto trans)That was in almost perfect condition too

todd,reher morrison has a nice hp chart which shows et/mph expectations,it's on there site

i think there 555 with 910 ponies should do it especially in that good air you guys have!!

have that motor built with isky ez roll lifters and a titan oil pump for extra longivity and your good to go

mike lewis could build one just as good,as could a few others

Got your message Todd I'll give you a ring tomorrow.

Anyhow, that conventional headed engine I posted about a couple times made 1100, running 8.70's at 156-ish... 8.80's in the heat(should really run .70's in the heat), at the time 3420 lbs.

So..... 1050-1075 could probably do what you need at 3400..... dyno numbers are dyno numbers bottom line you need a conventional headed engine to run 8.80's at 3400.

I don't think you're looking at much of a cost difference between 1050 and 1100.... it'll just be the matter of some details in the manifold, camshaft, and decision making here and there.......... of course, it's all CID related too..... 600 inchs is less money to make 1100 than 500 inchs is....

I don't think you're asking a lot really, but again depends on the CID.

Oh, and Welcome Joe! Been a fan of yours for a long time.

The first time I heard about you was when you, John Lingenfelter, and another gentleman did a contest in one of the magazines, maybe early 90's about who's theories would make the best combination in a drag race or something of that nature....

Yours was a high winding small block and the other guys had their own theories which would be better at the track....

Of course when you stated something to the effect that you have to wind em up I was hooked.........

I know Chevys are cheap to build, but can an 1100hp 600ci engine be built for only 15K???

I assume pan to carb from scratch.
I had said "about 1,000 HP."
Shafiroff claims 965 HP in a 582 for $12,450 plus carb and ignition.
Reher-Morrison claims 950 HP in their 565 for $15,495 (but I think carb and ignition is on top of that).

So 15K might do it, but 17K probably gives you more directions to go.

For some reason I couldn't get YB to load on my computer to save my life last night.

OK, this might be long winded, so bear with me.

A good friend of mine has a 565 with a Reher Morrison top end kit which has Dart Pro 1 18 degree heads and 15 to 1 compression. On his engine builders dyno it made a conservative/honest 950 hp and 750ish ft/lbs of torque. His car weighs 3550 lbs w/driver. On C14/16 it was running 9 teens in the heat at around 146 to 147 mph. With a change to Q16 it'll now run mid/upper 9.0's in the heat at 147 to 148.

I've been looking at 565's or maybe 582's most between 950-1025 hp. Just recently two racers both made comments to the fact that the 582 wasn't that great. Something about bore side loading with the longer stroke and short rod/deck height. I don't know how much truth there is to those comments.

R/M 565 is rated at 950hp+ and 780 ft/lb for $15,495.

Sunset has three I"m looking at.

565 Warrior rated at 940 hp and 765 ft/lbs for $14,499. (as cast Brodix BB3Xtra)
565 Pro rated at 1005hp and 785 ft/lbs for $18699 (CNC Brodix BB# Xtra)
582 Pro rated at 1025 hp and 795 ft/ls for $18,999 (CNC Brodix BB3Xtra)

Now, I'm still trying to get over the sticker shock of these things. But after sitting down and running some numbers I came to realize I had $13,000 in my old 461 bbc. It was spent over a couple years, not all at once.

The Two Sunset Pro versions can be had for less $$$ by eliminating the jesel belt drive, crank trigger (have already) and vacuum pump setup (have) taking over $1500+ off the advertised price. I wasn't really looking at 582's, but it did catch my eye that the 582 made 20hp more, only 10 ft/lbs more torque for only $300 more than the 565.

Anyway, I have also considered building my own from scratch. Running the numbers this way I come up about $1000 less than the crate engines, but my numbers don't include dyno time ($800/day) , no machine work, nor any cost overuns which my projects always seem to have. I also have doubts that I as a racer/enthusiast could build something in line with the race builders ower with off the shelf bolt together parts. I can't afford to make a combination mistake and be down on power forcing me to replace expensive parts to make corrections.

Budget wise I'd like to stay in the $15-16k range if possible.

I have another buddy that has two Schmidt engines. One a 572, the other a 555, both run in his 3600-3650 lb G-body. Too my knowledge he hasn't really made any all out runs recenty, so I can't easily compare power to ET/mph data. He runs index stuff and detunes most of the time. The 572 made 1011hp, the 555 made 959 hp with no pump, so figure 980ish with the V/P.

most of those combos mentioned might make close to the hp but some of the parts are not that great especially the shafiroff.i would at least want a callies magnum crank and top shelf rods like a oliver billit or grp alum if you want to go that route.also dont think those prices include shart rockers and a few other parts that should be in a motor like that if you want it to last.schmidt has a 584ci conventional head motor on special at around 18k claims 1100hp but still needs some upgraded parts.
