Howdy,
I am in the process of building a 418w. The kit is from Scat. The car is going to be a Sunday driver and taken to the track here and there. I would like to have a Solid flat tappet. I dont have the budget for a solid roller "Maybe down the road for that" Also I dont want to run a loose converter. Is there a cam that is good from 2500-6500?
Hear is what I have.67 Mustang
2500 stall
4.30 gears
28x13 tires
Ladder bars with coil over's
69w block
10.5:1 c/r
Cast Dart senior heads. Stage 3 porting from Keith Craft.
Victor Jr. manifold
no carb yet
6208 headers Thanks for the help,
Jason

My 408W with 10.6:1 stage 3 Perf RPMs likes the Perf RPM cam (224/234) with the C4, 2500 stall. No need for solid lifters, go with hydraulic for the maintenance factor. If you are worried about losing the performance sound of the solid lifter, your 400+ cubes will make up for that.I would not go any higher than a 230/240 cam for a street car and your CID.

Yikes, I just noticed that you have 4.30 gear. Assume you are runnig a standard C4 tranny with 2.47 first gear? If so, you can cam a little higher than my post suggests. I would reccomend you limit your duration to 245 @ 050..I am still running my 2.79 8" rear and the torque I have with my cam is impressive. You will need less torque with that diff. PS I can smoke the tires in the first 2 gears even with the 2.79 and it spins both tires (275/60/15) even though I am listed as an "open" diff. Torque still applies to a cam this big when you have the cubes.

Do you have any vacuum requirements?
Idle speed you wish to have?
The Isky Mega 280 with the 108LDA should work fine.
Also the new Comp Xtreme energy series
like the XE274 should work well also.

I have a C6. Not sure what the gearing is. I bought a Erson cam from Alex"Money Maker some time back. It's [email protected] I might be using that but was looking for any other sugestions.
Thanks

I thought Alex quit making cam recomendations 
I would run the Erson then.
Alex seems to have a good track record....

I re-read the first post...SOLID cams...
I have Juice cams on the brain....
The Erson would be streetable in a 418.
Would still make enough power for the strip providing you have adequate heads, tuning, etc.....

Have you ran your car at the track? What is it in? Thanks,

I bought the cam from Alex to put in a 351w non stroker but then changed plans and went with the 418w. Just wondering if it will be a the choice cam to put in. I thinks it 292/544intake and 544 exhaust.

Skeeter,
My car is a '68 coupe and I haven't gotten it to the track yet. Best estimates are about 12-13 sec on steet tires, maybe about 115 or so in the 1/4. I put a hole in my radiator recently (really stupid mistake) and haven't spent the coin to get it fixed.

This cam will work fine in your stroker.  SteveW

Steve,
I would like to go bigger but am not sure how big to go with my current specs. Any suggestions? I will be sticking to a flat tappet not a roller because its a bit to much $ at the moment for me. Thanks,
Jason

You will likely have to go to looser converter if you go much bigger.
Hey, you already have the cam, run it and change it later if it seems too mild.
It's much better to be sitting in traffic with too small a cam than too large.

Jason, You will need a looser converter with the bigger cam. 3000 stall + should do the job, I'd go with a 3500-4000 stall and it will still be ok on the street. (Not a daily driver)  SteveW
