My goals are the following:
1. Definitely streetable/reliable(summer daily driver/weekend racer).
2. 300-350 RWHP(or more, whatever is realistic).
3. Would like to keep the compression ratio down if I decide to add a blower in the future.
4. Budget of $5000CDN(roughly $4000USD).
5. I'm setting a deadline for June/July...I hope 
I've already ordered the stroker kit from Eagle and i'm pretty lost trying to figure out a good head/cam/intake combination. I've been leaning towards the Twisted Wedge top end kit from TF partly because it seems to be a complete kit and comes with everything...pretty simple. But how efficient will this combination work with a 347? Will the kit cam be sufficient? Or should i take a different road with individual components instead of a kit?
If that's the case, I realize that I have endless combinations. I noticed several of you use the AFR 165s and seem to recommend them to alot of users. Would these be an efficient head with a 347, or would the 185s be the better choice? Is valve float still an issue with them above 5000RPM? What intake/cam would you recommend with them? |
In a 347 application and from what it seems you want, I don't know that I would do a TFS top end kit. 347 is going to want to breathe. If you did the TFS top end kit, I would recommend a port job on the heads and ditching the cam for a custom.
I would consider the AFR 185 heads (maybe even the 205's), custom grind camshaft, and at a minimum a Trickflow track heat intake (I, personally would consider a TFS-R intake)
Also if you already have the stroker kit, then I assume you already have the pistons, so part of your compression factor is already done. Do you have pistons and what are they? Dished, flat top, or dome?

3. Those of you using the twEECer, have you had much luck with it and what are your recommendations? I'm very interested in tuning and would love to learn more about it in the future. So it's definitely on my "to-do" list for this build.
4. Will the stock 5spd be strong enough to support the increased hp?
5. Any clutch recommendations?
Basically, i'm very open minded here and I would love to hear everyone's opinion! If anything else comes to mind, i'll post it.
Thanks for the help

1) at least 30's
2)yes you will need an EEC tune.
3) if you are willing to learn, the Tweecer R/T is a great tool for the money. Plan on getting a wideband 02 sensor setup that will datalog in the software. This will save you a massive amount of time.
4) I can break a t-5 in a stock 302
5) I have used King Cobra , Super King Cobra, Centerforce, and now Spec. I like all of them. Power output is what its all about with a clutch. Centerforce dual friction has the lightest pedal effort but after inspection when the throw out bearing seized up in about 5k miles, it was not enough clutch for my application but I think it would do well in a 350rwhp engine.
