Pump gas BBC street motor

[Rommel Racing]

I run a car set up just the way you are planning to go,it is a 3475lb(w/driver) 67 camaro with stock suspension. It has a 10.4-1 compression 515bbc based on a GenVI GM block 4.530 bore 4.00 stroke,Dart 335 cnc'd Pro 1's, Edelbrock 454R intake,Pro systems Dominator,Comp cam extreme energy street roller 266@.050I 272@.050E .677I .688E 112 lobe.

It is not anywhere near a daily driver but it runs very nice on the street and gets 10mpg if I cruise under 2200rpm. At the track it has run 9.89@137.80mph and with a 150 shot of nitrous it went 9.27@147.42 running on 94 octane pump gas.

Just providing this info to give you some more ideas.

th400 or glide?

That sounds like a badass ride got any pics?

[Rommel Racing]

It runs a th-400 with a 4200 stall 9" convertor,4.10 gears,and a 29.5x10.5 radial slicks.

Here's a few pics for you.

Wow that thing is beautiful!!!

[3V Performance]

What size headers are those? Do you have to run muff's?

Real nice car..

Real nice car..

Some videos would be killer!!!

[Rommel Racing]

Thanks Guy's, I'll see if I can find some video for you.

L89, the headers are 2.25" with a 4" collector.......I used to run a heads up class a few years ago that required mufflers...I don't race heads up anymore but always run the muffs anyhow....not quite as loud I'm sure

Thanks,

Steve

Steve , Do your time slips show your 660 ft times? If so what are they?
Thanks, Chuck

[Rommel Racing]

Hey Chuck,I been without my computer for a few days sorry.

On motor only it goes low 6.30's@109 and change.

On 150 shot it went 5.95@118.62mph.

Make any runs with yours yet?

Not yet , Hopefully soon.
Thanks

I have the moroso sliderule too but I don't have total faith in the car getting everything out of the motor like a stock eliminator car would so I figure I should give myself a nice 100 hp buffer zone.

What do you guys think of the Shafiroff 540 motor? supposedly makes 695 hp[/i]

100hp buffer zone? I'll give a street car 30 maybe 40hp buffer zone, because their not ganna work as well as a strip only car because of gearing / stall / exhaust.

On the Shafiroff, I believe they're really overrated in HP.
A local here got their 695hp 540 in a 69 chevelle, it ran 11.30s @ 118 - it was a total turd. This was with a their 1050 Dominator, good fuel system, good exhaust, 10" & 410s. I've hear this happening with others, so to me the Shafiroff stuff is very overrated. Its always better to build your own, unless you have a good shop workin with you.

Wow that sounds familiar...I have a friend who spent about 15,000 on a Musi 555. It was 10:1 compression with Edelbrock/Musi CNC 24 degree heads. Musi roller cam 270/278 @.050 693 lift. CNC'D Super Victor and 1250 Dominator. In a 3600 lbs. 1968 Camaro 4500 stall th400. 4.11 gears and 33 tall tires. it went 10.60 at 128 mph. My friend went to Musi's shop and watched it make 790 horsepower. A little disappointing.

Sent you all the info and some Pics.

I'm relocating to Ft Worth, so hopefully we can meet up soon!

See ya,

JIM

Hey Jim, You're just around the corner from Ed now aren't you? Your have head porting friends from the Sam's school probably made your motor a lot faster. If our car weighed in at 3200 lbs. i'd get the modified Edelbrock heads from Curtis Boggs in a heartbeat, i think they should make killer power and the price is right. A local Camaro racer bought a 509 from Reher-Morrison and it has already run high nines @ 136 so they can build what they say but are a little more expensive than some other builders. The C. Bogg head on top of a 555 or bigger should easily make 900+ and might run eights on the motor. I'd get big inches, with the slightly shorter stroke which could be built with a short deck block if one wanted.

I don't know, sometimes it' better to do your own research and apply, i know guy's who spent lots of money on motors that they ordered and were disappointed, i truley built threw out the years some of my own combinations, and my camaro went 10.33- motor speck was 406- 12.1
400 transw/brake-4800 stall coan converter- 4.88 gearsw/ 31x18.5 hoosiers- cam-@50 was 272in 284ex 654in-645ex on 108lc and on nitrious car went 9.42 w/200 shot- the kicker is i used to cruise this thing all the time, suspension was a four link and i played with the instint center to make sure this car would hook, i ran a 2ths delay in the nitriuos to make sure the tires wouldn't unload on launch, the motor was about 550-575 hp, pro1 heads
so with 600 hp theres no reason you can't run in the mid to low 10's, if you apply different stall and gearing it is possible.

Allright I have decided I want to put together a street machine that will see the track also.

The following limitations apply:
93-octane
Needs to be drivable on the street
Solid rollers are fine
Prefer stock angle heads (BMF, Pro 1's, etc)
9.8" deck block

This will be going in a 3200 lb stock-suspension 91 stang GT.

I want it to go in the 9's on horsepower and be able to get sprayed into the 8's on good gas. This will see probably 50-100 street miles a week and the track maybe 4-5 times a year.

Budget is 12k and that includes distributor/carb setup.

My initial thoughts are 582 inches (4.600 x 4.375), dart big m or merlin 4 block, BMF 350 cc heads, eagle rods/crank, and some pistons (JE, Ross, whoever). Shooting for 10.5-10.75:1 compression.

I am thinking I will need 700-750 at the crank to go 9's at 3200 lbs with a glide and a ford 9" making up the rest of the drivetrain.

What would you do given the budget and other limitations?

You could actually build a BBF cheaper and make more power per $. But that's your call. Times have changed, a lot.

Last week I had a 505 inch BBC (4.350 x 4.250) on the dyno and made 700 hp @ 6200 rpm on 91 octane. Single 1050, 258/260 @ .050, 2" headers (682hp with 1 7/8 headers but picked up 20 lb/ft below peak TQ.)
Engine idled at 1000 rpm.

The owner is a friend and it's going in his 84 Chevy PU that he drives on the street and competes in a sled pulling street class. We didn't build this engine so I don't remember everything in the engine, but it certainly wasn't anything special. This wouldn't be too expensive to duplicate.
