Yeah that was the idea. And since the local engine guy builds a lot of Mopar big block engines I'll loan him this valve cover so he can use it for dyno testing and engine break in. A lot of times customers bring in random valvetrain parts and we might be able to solve problems up front rather than down the road by double checking the oiling before the engine goes out the door.

Any chance of trying out the TF hyd roller cam? It's smaller than you have been using, but I curious as to how much power it really can make.

Andy - another cool AR product with the clear valve cover. The ported M1 intake looks awesome! Looking forward to the results vs the untouched M1.

Who's rockers are those?

I don't think I'm up for testing that cam. It is 20 degrees smaller than what I'm currently running so I think it would kill off a ton of power. Probably be a smooth running tire frying monster in a street car though.

No problem, They claim 620 HP with the TF heads and that cam on a 10.5:1 440.

The Trick Flow intake showed up today. Nice looking part. It is 1/2 inch shorter than a Victor 383 so that might help some guys with hood clearance issues. Also, the TF doesn't have the "eyebrows" in the plenum that make the Victor intake look so awkward. I'll get it on the dyno in the next couple of weeks and we'll see how it does.

I believe their 620 HP claim. I bet that cam in my 470 would also make about 620 hp. I'm making 685 hp with a solid roller that is 20 degrees larger as well as a Dominator carb. If I used their cam, intake and carb I'd probably be fairly close to 620 hp also.

yeah Andy, whos rockers are those?

Those rockers are made by RAS.

Yep, those are stainless steel investment cast rocker arms from RAS. I don't think they are available anymore. I think they were the very best shaft rocker arms ever made for BB Mopars but they were expensive and rarely in stock. I used to have several sets of them but I've sold everything off but this last set.

The porting that Wilson did on my M1 intake picked up 30 hp. Engine made 715 hp this morning using the same 1050 Dominator that I was running before. Gasket match still isn't perfect so there is probably a little more power hiding in the combo.

Nice, Wilson did a great job. Did the Peak HP rpm change as well? And did you throw on the trick flow intake on afterwards to test that too. I know I would of had to.

No the peak rpm is not moving up. Best pull was 715 hp @ 6500 rpm so the engine seems to be "tuned" for that rpm and isn't changing. I was hoping that the ported intake would move the rpm peak up a few hundred rpm so the power numbers would move up but it didn't happen.

Impressive numbers.
Was there a gain in leak TQ as well?

Is the TF intake going on next?

Did you get another 4500 carb to try? (I can't recall if that was part of the plan)

I like the headers what size are those? They should up the numbers some.

I tried two Dominator carbs. A 950 and a 1050. The 1050 carb made 10 hp more than the 950 carb.

I did also try the new Trick Flow low deck intake. This is a very nice intake, I think it is a better design than the Victor since it doesn't have the big eyebrows in the plenum that the Victor has. I used a new 1050 AN carb from Quick Fuel. This combo made 690 hp @ 6500 rpm.

Pretty impressive gains with the Wilson M1. Almost makes it worth the money

The engine builder I work with does a lot of 420+ inch SBC circle track engines and they typically see 20 to 30 hp increase from intake porting. The circle track guys tend to get their intakes ported but the drag race guys don't.

I'm thinking about getting the Trick Flow intake ported. I'd like to get that combo up over 700 hp also. I think the Quick Fuel 1050 carb is capable so it is just the intake that needs a little help.

Did you try the 1050/4500 on an adapter, on the TF manifold?

The TF intake 1050/4150 combo was 5hp better than the unported M1/4500 combo?
