Re: Let's build a drag race 8BA engine

I don't know. I haven't poured any gas in one since the 50's except down the injectors to start.

Re: Let's build a drag race 8BA engine

Conversion from race gas to straight alcohol is good for at least 10% increase in hp. assuming optimum tune for each.

Re: Let's build a drag race 8BA engine

Yes, you are right. I was refering to Smokey and the Hudsons. I quit following NASCAR after that.

Re: Let's build a drag race 8BA engine

These are race engines. We run alcohol.
I do have one customer that runs 118 race gas and it works fine.

I seriously doubt you will find any useful information on advanced engine development in...

Re: Let's build a drag race 8BA engine

Ah, another expert has come aboard. Welcome.
It is common practice when a new poster comes on to introduce and tell a bit about yourself.

By the way, 14 to 1 or more has been quite possible since...

Re: Let's build a drag race 8BA engine

There were never any forged flathead cranks.
The steel Mercury ones were shell molded

Flat tops give us 14 to 1.

Re: Let's build a drag race 8BA engine

Frank,
The lift figures of that Howard cam are very similar to ones used by the DO Hal for mile track events.

Re: Let's build a drag race 8BA engine

Today's trivia lesson.

Howard Johanson (Howard's Cam's) was a neat guy that drank beer from quart bottles.

Re: Let's build a drag race 8BA engine

On a 1/4 mile dirt track I would gear it to run from 4000 to 6100.
With a good car, you should be able to flat foot it all the way.

Re: Let's build a drag race 8BA engine

Well, I feel the same way. Ron, JWL, I and others have shared much info by email over the years. I have learned many things from them and I hope I have been of help also. I hope to meet them in...

Re: Let's build a drag race 8BA engine

"Being a Flathead is definitely not going to be running at 7000/8000 RPM".

This part of your statement is totally wrong. An all out vintage circle track engine will have the hp peak in the 6500 to...

Re: Let's build a drag race 8BA engine

We have an old Stewart Warner. Have to lift the crank by hand or hoist over to the drill stand. Good upper body exercise.

Re: Let's build a drag race 8BA engine

I have been doing it since the first time I ran a balancer in 1954. I have never heard of anyone doing destructive testing to find the ideal percentage.
We use 70% for some single cylinder engines.

Re: Let's build a drag race 8BA engine

That is not just your opinion. Also mine and several builders of 410 sprint car engines. I use 55 though.

Re: Let's build a drag race 8BA engine

Anything is better than stock.

1- Straps with screws. Good
2- Simple center strap girdle. Better
3- 2 steel caps. (front and center) Rear with strap and screw. Better yet.
4- Full pan girdle...

Re: Let's build a drag race 8BA engine

It depends on the size of the engine. Simple math will tell.

Re: Let's build a drag race 8BA engine

It is simple math. A flat circle has less area than a spherical (raised) circle.
To do this you need to either fill a dome head and machine flat or make new heads with no dome.
Another advantage of...

Re: Let's build a drag race 8BA engine

I don't know who is doing welded cranks now but I used to get them from Hank the Crank. Whatever crank you choose, when you balance it, you want to make the bob weight as light as possible.

Re: Let's build a drag race 8BA engine

If you do not want to weld and re-machine the heads for flat top pistons, you can run av-gas. (100LL)
It is MUCH cheaper and will work with 10 to1 compression and your Edelbrock heads very well....

Re: Let's build a drag race 8BA engine

Ronnieroadster has a good budget build suggested.
One place you do not want to skimp on though is the cam and valve train.
A 425 with lightened stock lifters is probably the best flat lifter cam...
