Hello,
Which cam should i use with 350, torker or weiand( single plane) intake , long headers, flowmasters, ported heads, 2000 converter 350 tranny and 3.23 gears. Please let me know your suggsestions.

Thanks

 

You've given good info, but just a few more things....

Carb or TBI?

Is this a street or strip car, or both?

What's the compression ratio?

What heads are these (besides ported)?

How much does the car weigh?

That should help us help you better.

 

I'd recommend a comp XE268. But your going to want more gear with a single plane intake even if its strip only. I'd dump the single plane no matter what, if i was me but its not so... Dual plane intakes today are far superior to single planes in every aspect. Even though single planes may make slightly more (2-4%)power above 6000, it does not overcome the power loss everywhere else in the power band.

 

The cam needed to really make a single plane intake worth while, will want more stall than you are using. I havea 2500 stall with my single plane torker, and long duration cam. This spring I will be going with a 3000-3500. Trust me, either go with a dual plane and a shorter duration cam, or get a bigger stall to match the intake and cam. Also, a single plane with the cam required to make it useful and the stall will want some hefty gears, what are you running now?

 

Well, i just want to build a decent street-strip car (300-350 hp). I have some opporunities: 1) 600 edelbrock carb or 750 holley
2) single plane intakes or get performer rpm 3) I have 882 ported heads at the moment or get 461 heads. The car weighs about 3300 or so. Which combo would be the best?

thanks,
Martin

 

RPM intake

Ditch the 882 pieces of ****, work over some 416's.

Xe268 cam

 

Anything is better than the 882 heads. As far as the single plane vs. dual plane, if everything else is set up right, the single plane is great. If you have one mismatched component, though, you will know it. People talk about alot about losing low end power, its really not that much of an issue. Sure, you will give up a little, but with the right cam and heads, you will more than make it up in the top end.

 

Maybe on a stock L98..

Better write this down on the calendar.. We agree on something.

See, everyone can agree on something!

 

i would deffinatly agree on the cam.for the intake id buy the proffesional products air gap knock off. they only cost $170. then i would use a 650 dp holley carb. you can get a remanufactured one for about $250,or hit the swap meets! for heads i would use the 461. its a great head for an old head. if you plan on spending money on them , dont waste your time you can get a brand new set of vortec's with a spring that can handle your cam and the machine work to the valve guids for less than $700. and the amount of power will be worth the extra money. use a profes. products vortec air gap , also about $170. that set up with about 9.8- 10.2 compresion will get you roughly 380hp+. also.....get a 2800 stall! you will be much happier with a car that runs low 12's than you will one that might get out of the 13's.

 

My only advise is go one step bigger than you think you want...
