I was wondering if these heads will work with a flat tappet cam? Is there a better head out there for the money for a hot street motor? I want something big enough to grow into and I'll be putting plenty of spray to it. I just don't want to have to change cams right now. These will be going on my '70 Nova in the sig. For when the time comes, can anyone suggest a good cam to go with these heads(flat tappet)? I like the looks of the Extreme Energy cams by Comp Cams, are they roller cams or what? Yes, I'm a dumbass. Thanks.

 

The track 1 heads have kinda big intake ports for a 355.....they are more suited for a 383 or bigger

They flow O-K, out of the box but the casting is pretty rough on them and they really open up with some porting

With some port work on my Track 1 heads i'm at 279/220 @ ..500 lift which is pretty darn good

i'm running a hydraulic flat tappet turbo cam in my motor

 

Thanks for the reply. Do you have another suggestion that might would be better for me? I'm figuring on sacrificing some on motor with the Brodix heads but hoping it will really come alive with the spray. I also like the Big Port 23* heads that Trick Flow sells. Thanks.

 

The big port trickflow are the same size intake port as the track 1s and i feel the track 1s are a better head out of the 2

for a 355 you dont need much head and its the exhaust you want to flow like mad for a nitrous motor

Just depends on what you really wanna do i guess and what you wanna sacrifice

There is a guy i know with a 355, 10:1 with dart un-ported 180cc iron heads with 2.02/1.60 valves, performer rpm intake, i *think* a 750 holley, and in a 3400lb thirdgen it goes 11.60s-70s on motor and 10.80s or on a 150 shot. Port the exhaust on those heads and the numbers will improve

If i were to build a fun streetable daily driver motor, that would be the combo

 

Thanks man, you're being very helpful. Right now the car is getting the roll cage installed so I have a little while to put some thought into which heads I want. I'm looking for some mid-high 6's in the 1/8 mile@ roughly 104ish on the spray(175-200, maybe 225 shot). I also want to be able to drive it plenty on the street with no problems. It'll weight in probably at about 3000lbs w/out me(160). I'm hoping some similar combos will put in their 2 cents. Do you know of a site that's more dedicated to old carb racing. I also need to look at my fuel system, I'm not sure of the differences between this and EFI fuel systems/pumps. Thanks again.

 

Look at the Track1 that's 100% CNC machined by WeldTech.

These are great out of the box. Exactly 215 cc intake ports and about 300 cfm (@28 " H2O) at .600 lift. Low lift flow is also great . They ain't cheap, but they surely do work.

BTW, a head was flowed to check Brodix/Weldtech's numbers and they didn't exaggerate at all; the flow was there. I've seen it dyno over 550 hp below 6500 and over 515 ft-lb on 92 octane all motor with less cam duration than you'd believe. It had over 450 ft-lb from 3300 to 6300. This was on a 365 SBC. That would yank your Nova around the street pretty well. As I remember, the headers were for a 70 Nova. Oh, yeah, this was all thru mufflers. You might not even need NOS!

Unfortunately to do this required an aggressive hydraulic roller cam and parts. That doesn't fit your plan. Probably neither does the price of the engine. At least $15,000!

 

Im at 292 @ .600 lift and i layed my airflow sheet over the weld techs and its pretty close.....just has a bit on my porter in the lower lift, but not too much

They are great heads. I had a friend who had fully ported track 1s on a 383 with a crappy single plane to fit under the hood and a decent sound roller....

car went 11.80s on radials with a 3:42 gear @ 118mph. With slicks it was going 11.0s.

They are great heads

 

What were the runner vols? @ 215 a ported Track 1 can't do that, that was the reason I ran them!

The M2 CNC versions are good also I'm just not as big a fan of M2.

on which combo? LOL

 

what was the runner vol on the 292cfm @ .600

The CNC Weld Tech T1's do that too but most T1's start out at 222cc's or 215cc's(earlier models) and flow less air.

The new casting flows 276cfm stock @ .600, so the port size has go to be bigger.

It all depends upon what you are using it for. HP level, rpm and displacement all have something to do with the optimum port size.

I have the earlier model T1 heads that started off with the 215cc ports

i dont know where they are at now.....when i go back to my porter to pick up my rocker arms i'll bring my heads by and ask him if he can find out

i'm guessing around 225 or so
