i have been looking at the victor pro head that curtis offers. the car owner is talking about swapping to big chief style heads but i think this is going to get more involved than he thinks. the paper work he got with car says the heads flow 390 don't know anymore than that. the engine is from oddy's i think. is it possible to go 4.0-4.10 with conventional heads. the car has best of 1.028 2.81 330 runs 168 mph 1/8 would like to run 173-174 mph.

heads

Lance the Victor head flows decent but unless you get a solid version they will crack.We ran a few sets. We got around 400 cfms but they only last a few passes before cracked apart.Leaked cylinder to cylinder pretty good also. the BB4 seems to be a killer piece as far as conventional
other than that the big chief style is the way to go,worth the money in the long run

Lance, you could also PM Camp Stanley on here. He's built/run nothing but blown/alky for years. He has a few customers I believe in Australia that have done very well with Dart 360's. He could probably make some recommendations.

You might want to look at the new Dart Pro 2's.

edelbrock victor or a gm 861 bowtie casting with the .750 raised exhaust port.the heads are the same. the deck isnt thick enough and it cracks in the chamber, most times towards the spark plug.
we even cracked some on low boost blown gas when the motor detonated. mine was alky with no water so i ran them cracked
I currently run a A.J. 481x in the red 57 thats a nice piece and easy to work on,so does little Camp Stanley

We ran Dart 360`s, with a PSI and ran well with them, and had no issues. We went 6.25 @ 229 with that combo, with a Bruno-Lenco set up. 20`s and 30`s all day long. Its a Pro Mod car BTW.

Now we have an AJ 481X. We have run a few 20`s, but really picked up in the MPH area, running 236+. Mainly due to the ability to actually flow the air the C rotor makes.

Lonnie Houde and Scott Filkins have been in the 5`s @ 242+ with a big chief head as well. If you need any help, check out www.LHPRacing.com and give Lonnie or I a call.

That was the Victor #77609 that had that problem, .. NOT the current
Victor 24* # 77419.

But that said, .. I would use a solid Dart 360 casting for this, ..
I do a bunch of those for blown alky monster trucks, and a few
drag applications. ( flow around 460 cfm @ .900" )

I've been through Oddy stuff and picked it up a bunch, ..
he doesn't really do much head work.
You might be able to reach your goals with conventional stuff, ..
but if you really want to go fast spread port can make a difference.
I build a 14* power adder head on a Solid dart casting as well.

Was about to suggest those heads as well. Bad to the bone.

for T/D racing, sometimes we have quick turn around times late in the rounds. Do you not worry about heat in the motor and oil with these solid heads. I assume you run no water through the motor with solid heads? never had any experience with solid heads and am fixing to be new to this blower stuff. thanks

Scott Braskett has gone 4.15 in the eighth with a 540 and a Dart 360's. They were ported by a guy that used to work as Sonny's. I will ask Scott for his info for you today. This is a really proven combo from the Camshaft to the heads. Scott has really refined this combo and has gone high 6.30 with it. He runs a 14-71 blower.

did they ge the exhaust port / gasket roblem fixed on the BMF? I know of several people here who got the BMF head and the exhaust port was larger than their headers on the roof of the port? they had to slot the header flanges to raise them to cover the port
