00:00 Hey everybody out in Mopar land, this is Johnny Hunkins at Mopar Muscle Magazine and today

00:09 we are here with Steve Dulcich of Engine Masters Magazine and we're actually on the set of

00:15 the Engine Masters TV show.

00:18 We are actually a Westech performance to be honest and we've got some special gear here

00:22 today.

00:23 We're going to put these to the test.

00:26 This is TFS's Powerport 240 cylinder head and their single plane intake manifold for

00:32 the raised deck wedge.

00:34 Steve tell us what we've got here and what the plan of action is.

00:38 Well I guess this is going to be a discovery for everyone here because this is actually

00:42 the first I've actually laid hands on these parts and seen them in person.

00:46 They claim that this combination will make like 600 horsepower on a hot core 40 combo,

00:51 maybe a little more.

00:53 Yeah 620 horsepower on a stock 440 seems kind of a fantastical claim to me but if it's true,

01:01 wow that's like a license to print money.

01:03 Well let's see what we have.

01:04 I mean the intake manifold here definitely looks like a 600 horsepower piece.

01:08 I've built several 440s that made that kind of number and it takes a pretty good parts

01:14 combination.

01:15 These big open sweeping runners, this is a really nice design.

01:19 Has a nice plenum and quite a high rise.

01:26 I wonder if they're going to do a low deck version of that.

01:29 I would imagine they would for all you 383 and 400 guys but look at that.

01:34 That's a nice large, that's probably like the max wedge size port there.

01:37 No this is a standard port window, that's the thing about it.

01:42 It can be ported out larger but stock port window.

01:46 So what do we got on the cylinder heads over here?

01:48 Well once again stock port window, you see all this extra material here from the roof

01:53 to the valve cover rail.

01:56 That gives you enough room if you really wanted to make this into a max wedge port, it can

02:00 be enlarged but really it's fully CNC maxing out the stock OEM regular port window.

02:07 Well that's great because that's going to fit the needs for a lot of guys out there.

02:12 You'll notice that it's a fully CNC port and it's pretty nicely done.

02:16 I mean I've done quite a bit of head porting on various big block Mopar castings and they're

02:24 really taking this thing out to the limits.

02:26 They've decreased the diameter of the oil hole that feeds the valve train that lets

02:31 them get a little bit wider in between two ports.

02:34 You don't have a big protrusion where the bolt is.

02:37 Yeah let's see where that is.

02:41 It's pretty much a straight shot there.

02:43 I mean you can see the back of the valve right here from the intake port.

02:46 You'll notice that it doesn't get any narrower from the mouth.

02:49 If you look at a factory head, as it gets around the push rod bulge, it bulges out in

02:54 here and you lose a lot of cross sectional area even though you've got full width here.

02:58 I mean you have all that air flow stalling on the back side of it.

03:01 Well here you've got full width all the way through so it's pretty nice.

03:05 We've got four valve springs on this thing Steve.

03:08 My guess is that we're going to have to spin this thing up well past 7 grand in order to

03:12 make that horsepower with just 440 cubic inches.

03:17 Yeah I don't know.

03:18 It'll be upper sixes.

03:19 This is set up for a solid roller.

03:21 That's what we're going to run.

03:22 We have a comp street roller in a 440 as our test engine.

03:26 So you know you can put whatever springs you need to suit your cam requirement.

03:31 What's really nice about this is if you look at any stock head from '68 and up, you'll

03:35 have a full dished combustion chamber like a bathtub.

03:40 And here we've got some squish area there, some quench pad.

03:43 Well a lot, yeah.

03:44 It's got quite an extensive quench pad.

03:46 It's kind of like a figure eight style chamber and it's fully CNC'd.

03:50 Well that really is Trick Flow's specialty.

03:52 They've really got that dialed in with a lot of their engine families that they cover.

03:56 We've got a 219 intake valve that's a lot bigger than a factory 208.

04:02 It's actually a lot bigger than the common 214 upgrade valve, 219.

04:07 That's a good valve size for a big block.

04:09 176 on the exhaust is just a little bit bigger than a stock valve.

04:14 You really don't need to go too big on the exhaust.

04:17 You're better off to use the available space to maximize the intake valve.

04:21 Well we're going to find out exactly what all of this is going to do very shortly.

04:24 So next time you see us, it will be on the dyno with Steve's stock 440, about 10.5 to

04:31 1 compression, right Steve?

04:32 Yeah, we're going to have to be careful.

04:33 It's the numbers motor out of my '71 RT.

04:36 Built it several years ago, ran it on the dyno and it's a pretty stock piece.

04:43 With these heads, it's going to be a real barnstorm.

04:48 That's going to be a fun little screamer, so stay tuned.

04:50 Next time we see you, it'll be on the dyno, folks.
