I have a set of afr 190's and will be having them worked. Afr calls for either a 1204 or 1256 intake gasket. Would it be ok to port match the heads to these gaskets or could I use a 1205?

I think the 1205 will be too big.
What do you guys think?

Also what port size intake sould I say with? I thougth about a Vic jr, but they have large runners. I also thougth about a Team-G with have a smaller runner than the Vic jr.

I need the intake I use to fit under my stock camaro hood.

Oh yeah, I will be using a comp xe282hr cam. It has 282-288 duration and .510-.520 lift. I have 1.5 crane gold rr's, but would consider going to 1.6's on both int/exh or split and do a 1.6/1.5 combo. With the 1.6 the lift will go to like .544/.555 lift.

I will be use 3.73 gears, 2800-3000 converter, a th350 and 26" tall M/T tires.

I could use some advice on the heads. Also would comp 987 spring be ok with the cam and heads?

thanks and sorry for all the questions and being so long.

 

Would a Vic jr #2975 work ok?

 

It will fit under your stock hood with a 3" drop base.

 

If you think 1205 is to big, a victor jr is also to big. I'd look into a Performer RPM (the RPM!!) or Weiand X-celerator (single plane). I have a torker II and the ports are stock size, so you do not want one of these.

Do you know the victor jr. is rated 3500-8000 rpms. Can your engine even achieve this RPM range? Your cam is kinda of small for this RPM range. You will also need to upgrade your valve train, like solid roller with some heavy valve springs.

 

I was just worried about being able to port the heads out to a 1205. I found out that it will be safe to port to the 1205, but not the 1206.

Yeah, I know the rpm range of the Vic jr's. The #2975 range is 3000-8000, its a little shorter version.

The cam has a 2200-5800 rpm range with the 1.5's. It will be more agressive with the 1.6's. It is also a Hyd roller cam. Comp has the 987 springs that will be just fine for this cam.

I have a weiand #7546 x-celerator, but it will not fit under the hood. I also have a weiand #7525 Street ram Team-G. It has a rpm range of 2000-6500. I may sell both to get what I need.

The Team-G fits under the hood, and seems to match the cam range. Im just not sure if it is optimal.

 

I meant X-celerator 7547, I do not like the 7546 because of the runner design. You can see the 7547 turns before the port so it goes straight into the head.

Is your team G manifold's ports close to the size of your head ports? If so and the RPM is in your range, that one will probably work better then just throwing on a huge manifold, you could lose power, bigger is not always better.

 

I ended up with the 7546 after buying some parts at a deal. The Team-G matches the heads fine. I may end up using it.

 

I used an RPM air gap intake and port matched to a 1205. I also did the chambers on the heads and picked up a little over 4% flow on the intake and 3.5% on the exhaust. They flowed only 4 cfm less that AFR's full CNC'd heads

The lift on that cam will be too much for the heads. Flow peaks between .500" and .525" depending on the actual head and the valve job etc..

Try to stick with a dual plane intake. It will make better hp/tq down low where you want it on a street car.

 

Will the cam be too much even with the 1.5 rr's at .510-.520 lift?

I will be having them opened up and reflowed, so I should get more flow out of them.

Do you know of any good dual plane that will fit under my stock hood?

 

I have the Performer RPM air gap and it fits under the hood of my TA and it's got a 650 DP with a 1/2" spacer and 3" tall filter element. Lift wise you'll want to stay with the 1.5's if you go with that cam. Duration wise that cam is on the edge of being to big for a 350, depending of course on how much you'll drive it on the street. You will need a little higher stall converter to make it work.

 

Going on port size alone the RPM Air Gap has bigger port exits than the Vic Jr. I just had my Vic Jr ported .025 smaller per port wall, (that would be .050 undersize in port width and height than the my AFR 195 ports.
I did run a Super Vic manifold and it was WAY to big for the engine. It's runner cross sections and plenum area are massive compared to a Vic Jr. Super Vics are intended for LARGE displacement small blocks. It just did not like to run good till high rpm (6500+) and really hurt the bottom end torque band.
