No bleeding here. I use high helix burs for bulk material removal that leaves a "sharper" finish, followed by finer cut aluma burs for a smoother final finish

👍🏼

Thank you. 👍🏼

Thanks and welcome.

I use a selection of carbide aluma bits, from Killer Carbide Burs.

@ChopperScott cool thanks

I appreciate it. Thank you.

I appreciate it. 👍🏼

Thank you sir. I'll usually spend a little time staring after I'm done porting. 😁

Nice job!

Rat Pack, left lane.

Thank you Karl. I had a hard time letting go of that manifold. That one was in my possession for over 25 years, running it on my own 355, before I finally spent some time porting it for a more serious combination.

Fronczak Racing has had excellent results with this manifold and spacer combination on his builds. I’m just adding a little icing to the cake.

It’s gone 4.90@@142 at 2600# naturally aspirated on a good prepped track. At some point, it may be competing in NMCA/X275 class.

@@ChopperScottThats eighth mile right…? How much you weighing in at? Holy.

@@ChopperScotthow much hp on all motor?

@@Jeffrey_Edward_Epstein Yes, 1/8 mile @ 2600#

Thank you sir. 👍🏼

Thank you sir. There is at least one manifold with my port work that has traveled the distance. ✈️

Glad you like it. 👍🏼

Not in stock. These 2907s aren’t currently available. The Weiand Track Warrior is a very similar design. You’re welcome to have one drop shipped to me for port work.

@@ChopperScott thanks Scott. I know about the 2907. I effed up not getting one local. Was discontinued.

Take a look at the Weiand 7623.

Most SBC manifolds start at $750. Pricing can vary depending on manifold and amount of work required for a specific combination.

It’s 3060# on the line.

Thank you kind sir. Your performance was on point. Glad you enjoyed it.

Thank you. 👍🏼

Thank you, kind sir.

Thank you, kind sir. Taking the same approach of making power on pump gas, a similarly scaled up big block would have the cubic inch advantage to make up for increased weight. The most important question is “how much money to spend?”

👍🏼 .012 and .026 on those runs.

Currently 434 cu in, 11:1, naturally aspirated, running pump gas.

Yes sir. That’s the plan.

👍🏼

I run an older set of Hooker Super Comps... www.holley.com/products/discontinued_product/parts/2239-1HKR

Depends on your goal. The BMP 4500 and Super Victor 2970 will handle over 700 horsepower n/a when properly ported. The P2E IronHide and Uratchko Hulk are the new kids on the block, and can support serious power, with only a port match.

@@ChopperScott drag race only engine in a 3000 lb foot brake car. Just looking to pick up a little ET and MPH and possibly switch to E-85 or alcohol

Are you currently running the BMP? You can reach me at 917-589-1278.

@@ChopperScott I will message you thanks

In good weather, this combo will run 9.80s… on pump gas.

11:1 compression, Sunoco 94 pump gas, with power steering. It’ll run 9.80s in good weather.

No sir. Standard bolt pattern with .250 raised exhaust ports.

👍🏼

Yes it was! Same here.

That’s awesome! He’s getting hooked early. Thanks for watching.

I have a 1979 gmc caballero Diablo that I’m putting a 406 in it he’s going to help lol

Outstanding! 👍🏼

Any time!

Depends on intake and amount of work. You can call or text me at 917-589-1278.

Yes. Bypass after the pump. -12AN in, -10AN out, -8AN bypass. 500 GPH @ 28 psi. Carb is regulated at 6.5 psi. Pump is capable of supporting 2000 HP running gasoline. Overkill for this combo.

That was a 10.118@131.13, shifting early on the 2-3 to remain slower than 10.00 for the class. Ran a 10.120@131.13 on the previous run.

@@ChopperScott oh nice
