I spoke to Artie from TrickFlow and told him that I was going to stroke my car out to a 347 in the future, run NOS and a supercharger. He took all of this into consideration and gave me the following package. Tell me what you think?

Intake: 51500002 Street EFI
Heads: 51400010 Street TW
Rockers: 51400510 1.6 ratio
Pushrods: 21406750 6.750" long
Camshaft: 51402001 Stage 1. 275*/279*, 221*/225*@.050" dur, 499"/.510"lift, 112* l /s
Gasket Set: 51400914 Complete set

By using our camshaft you will make 395hp @ the flywheel.

So is this right, he said I'd be pulling this w/o the 347 stroker. True or not?

I would use that and a different cam

have the heads ported when you go 347 and they will work well.

The cam is small for a 347. The car should make the 395 FWHP he told you about on a 347. On a 302, you're going to need some help. The manifold is also a bit small for the 347. You may want to look into the Track Heat manifold, however, if you are not going to change the cam, I wouldn't change the manifold either.

One question - why a supercharger and nitrous? I hate to be negative here, but unless you get the car tuned by someone who really knows there stuff, and doesn't sell theirself to you, you just asking for trouble.

I have a buddy putting together a 347, he's just going to use the TFS engine kit, which is designed for a 302, and then a better cam. I'd think that even box stock twisted wedge heads would be about perfect for a 347.

They're more than enough head for a 347. If it's a race 347, then that's something different. But, if the car is going to be driven on the street, the TW heads are plenty.

i said super and nos because that's what i wanted, but since i'm not too familiar with this, i'll just keep the charger. so for a cam, which one would you recommend?
i spoke to summit and put this together:
HEADS
289-351W, 61cc combustion chambers, 2.02 in./1.60 in. valves, assembled, Track Heat aluminum cylinder heads
INTAKERunner: Small cross-section with 12 in. runners
* RPM range: 1,500 to 6,500
* Throttle body inlet: 75 mm
* Port size at mating flange: 2.0 in. x 1.2 in.
* Overall height (when combined with corresponding lower intake): 10.2 in.
* Finish: Non-powdercoated
CAM
Specifications:
* Advertised duration: 275 intake/279 exhaust
* Duration at .050 in. lift: 221 intake/225 exhaust
* Gross valve lift: .499 in. intake/.510 in. exhaust
* Lobe separation: 112 degrees
* RPM range: 2,000 to 5,500

I'm having my doubts about the cam though, what do you all think?

A wide LSA will work well. How much boost do you plan on running? The more boost you run, the less cam you need to get to your goal (if you have one). Something like a 216/222 cam would be an all around good cam. TFS heads can get away with between 6-10* more on the exhaust side because of the awkward flow numbers generated from the port volumes and valve sizes.

Wow, really? My 302 cam is bigger than that, and I always considered it on the small side. Learn somethin' new every day

after i do the stroker with the h/c/i, i'll be a little short on dough so i want a cam that will still give the car the balls it needs and after the super, still work fine. so you recommend the 216/222 cam?

I have always thought that a supercharger doesn't need much duration. It doesn't need the valves held open long because the boost is being stuffed into the cylinders. Supercharger cams seem to have a shorter duration with a higher lift. I assume that the car is going to be driven on the street so you don't want anything too radical. Yes, it is a very small cam, but I'm not sure what he wants from the car. Who knows. That is just what I would use. If you want something "special" from the car, that cam will get you into the 11's. My cam is almost 10* more on both the intake and exhaust side .

so this cam will work for before and after the supercharger or should i get the best for application and then buy another one for the supercharger?

Either way, it seems that a wide LSA cam is going to be good for you because you drive the car on the street everyday. With a wide LSA (greater than or equal to 114) you should have no problems with idle surge in an N/A form, and when you put the supercharger on, the cam (with a wider LSA) will be better suited towards a supercharged application.

afm B31 or B41 cam....plus a wider LSA will not bleed off cylinder pressure which is good on a forced induction set-up

Redsnk95, I love yoru car. You have everything that is pon my future plans wishlist.

how many pounds are you running? does the T trim directly swap out with the s trim setup?

I was going to run mild boost 10 on AFRs 185s on my D&D for a while and then get a Dart block and up the boost.
