why does the intake have injectors and such ??
sounds strong , what kind of torque and rpm range ?

It's my friends bullet, not mine. I did try to hi-jack it from him! ;)
We did a carb vs. EFI comparison on the dyno. This build will eventually be in a Super Chevy article. The carb made more power than the EFI. :(
We will be running the EFI on it, that was the plan all-along. It will also have a small shot of Dry nitrous on it later. He needs to get used to the power first. This engine makes the same power N/A that my SBC makes with a 250hp shot!

Keep us posted on the progress, are you going to have the engine in the car before the end of the season? I would like too be at the track that day to see that baby run.

ya i,ve heard that before , the efi just gives you more accurate tuning skills with the computor but may not give more power ##s

Good job to Larry & the guys at Pro-Motion Engines on this Brodix 18 deg small block monster.
What was the min. CSA in the intake port on that set of heads?

The min csa, that set to Pro-Motion specs on those heads. All I can say is that the heads flow around 370cfm, 2.180-1.625 valves. Pro-Motion will use cylinder heads out of the box or will custom port them if needed to make the horsepower.

I thought those heads and intake were ported by Wilson??
Turned out good regardless. :cool:

Yes, Larry from Pro Motion sent them to Wilson and it was decided that to support the engine size which "grew" from your typical SBC 414-434 size to a Tall Deck 455, they would need porting and a matching intake to support the new engine size.
This is a fairly low-rpm engine for a SBC. We "only" turned it to 8000rpm. We "only" plan on running it through the traps at 7500, until a small shot of nitrous is put on there. ;)

Yeah, I thought this might be the piece that was mentioned in a thread on CU's N/A forum.
It sounds similar to my 440, but a little bigger bore/stroke. And I agree, 7700rpm pk hp is "fairly low-rpm" for a SBC. ;)

I`ve been running at Island since 84 and never seen anyone not stop at high speeds. A few years ago a woman ran a jet dragster at 300 MPH at Island and she stopped it to.:rolleyes: Unless your talking 400-500 MPH then it might be a problem.

Well hell I need new brakes, there is no coast time at all for me, but a chute help a hell of allot, I'm use to Atco or E-town, last time I was at Island I almost ended up in the containers at the end of the trap. Must be my fear of the containers, have seen some racers end up in the woods up there.

Saw that engine in person a few weeks ago and its a killer piece! Larry is working with me on a new little m/brodix 406 this winter to replace the stock block 406 he built three years ago. Hes the man! That 406 is still running strong after over 300 passes and numerous street miles.

just curious are the heads 18x or 18 deg clone
Mike Beck

Not exactly sure which Brodix 18 degree heads they are. The owner was finally able to get to the track and make some passes. Car went 9.2 @ 149 back to back at Island Dragway. It's going away for the winter. We'll see what else we can wring-out of it next year. Not bad for pulling the engine off the dyno and sticking it in the car. I say 150mph comes before 8's. This is all footbraking on a 30 x 10.5" tire, 3300+lbs.

I don't know what issue it will be in. I know a ton of time and effort was spent doing this engine. There were a lot of companies involved with this build. Practically nothing was buy it and bolt it on. Larry, the owner of Pro Motion Engines, had to spend a LOT of time getting this thing right. Tall deck block, cast manifold, lots of custom stuff had to be done. All I can say is that Gaby at Wilson Manifolds did a great job on the heads and manifold and Larry did a hell of a job making full use of what Gaby gave him! I think he has more lobe lift on that cam than I have in total lift in my engine!
With the EFI it starts and idles very, very nicely. Wouldn't even think it had that much cam in there!
Stout yes, but what is it gonna cost me to have a duplicate built?
Mike Beck
11-25-2009, 11:14 PM
Call Larry at Pro Motion and talk to him. Power ain't cheap!
Agreed and I'll bet this engine ready to run cost at least $18,000.
What is the owner going to run with it?
Mike Beck
11-26-2009, 10:59 AM
The owner will race it in Pro (no transbrakes or 2-steps allowed), 9.00 cut-off. Maybe I'll get him to put mufflers back on it and race Top Street also. No ET cut-off in that class but mufflers required. We can use 2-steps and Trans Brakes in that class but he doesn't have one yet.

Larry at Pro-Motion engines built two engines for me, and a third one on it's way, you get quality performance with a long life span. He like to keep every thing on point that leave his shop, never nothing half ass, the man is a perfectionist. He not cheap but he is willing too work with you so give him a call, when he build your engine, you will be very satisfied with the performance.

I'm on the brakes right after the stripe and stop fine. Still have the stock front brakes in the car, too. Haven't pulled the chute yet. Brakes are on the toasty side after I get back to the pits mind you, but she stops without the chute.
4 BOLT
11-26-2009, 12:21 PM
Yeah you have to be on the brakes right when you hit the trap, no time to coast at all.
VegaEddie
11-26-2009, 01:34 PM
I'll wait a split second just to be sure the chassis is settled after I lift, but then it's hard on the brakes. If I'm on the binders hard enough right after the pass, I usually have just enough room to coast at the very end of the shutdown. In other words my speed is typically low enough at the end where I can coast around the turn off and begin taking the belts and helmet off, etc. That said, we may be upgrading the front brakes over the winter because I'm sure Chevy never intended the stock front brakes to stop the car within 1800ft from 155mph. :-D
Can't wait to see how that 455 small block likes leaving off a trans brake!:cool:
Mike Beck
11-26-2009, 10:34 PM
How heavy is your car? His is 3300 lbs and has Wilwood brakes all the way around and said without a 'chute he prefers not to race at Island.
VegaEddie
11-26-2009, 10:41 PM
3040 with me in it. Stock brakes up front and Wilwoods on the back. 153+mph. If you're used to a longer shutdown, then Island may scare you. I've been running at Island for about 17 years so the short shutdown is just something I am accustom to.
We have one guy who runs a blown/alky injected BBC Camaro there that routinely goes 7.70s. He typically uses his chute but has had it fail to open at times. I've seen him stop without the chute at 170+mph. Again, the shutdown is just something you have to be ready for and used to.
Mike Beck
11-26-2009, 11:37 PM
Yeah, just like US-13 (Delmar)............. I have a bunch of friends that race there but only one of them is close to 150mph. They all like E-Town for the long shut-down area for sure.
