I need some help on deciding a plan for my car. I have the motor out of my car for a rebuild. I currently have the trick flow track heat top end with all of the assisted bolt ons. I'm having trouble deciding if I want to build up the bottom end and stroke it, but would say a 347 be good with the top end I have? I've also thought about just buying a stock rebuild kit or possible putting dished pistons in the car and running a nitrous kit i've had lying around, and later on either turbo charging or supercharging it.

What kind of numbers would i be looking at for say...

347 stroker with TFS top end. and would i be able to run nitrous on it safely?
302 with TFS top end and 100 shot (or whatever highest possible to be safe)

I'd love to be around 375 rwhp, but don't know how easily that will be without something breaking with what I have. Will i need some better internals or can stock handle that? Any help will be appreciated.
Thanks,
Jake

I would just to the stock rebuild with your tfs top end and put some spray to the motor and you'll reach your goal.

I wouldn't worry about putthing better internals in the motor because the block is the weakest point in most cases

Either one will get you to your goal. Difference being that with a 347, you'll have that power all the time as opposed to only when the nitrous is on.

You think i'd be around 400rwhp with the 347? The track heat system wouldn't be choking such a large cubic inch would it? I mean it is build for the 302, but also for the 5.8 so idk. You said if I did run the stroker kit to not run any type of FI. Would it be recommended to run a higher compression piston then? Of course then I have to compensate for ptv clearance. The kit does sell a dome piston, or I can always place my own order for pistons.

Idk if I like this... It just seems like i'd be able to run better with stock internals and spray? I'd love to be able to spray a 347, but I still want to be safe about it you know? I'll be running a c4 behind it and i'm not too sure on gearing yet, probably around the 4.30's area. I'd like to be able to run mid to low 12's. Possible?

Substitute the cam for a good one and you can make close to 400whp with that top-end and a 347 if everything is set up right. 93 hatch makes 388 to the tires with tf170 heads and a 347. Granted that C-4 will eat a little more HP that a stick trans will. In any event, with a decent 60', mid 12's can happen with that set-up if you shut down at the 1000ft mark. You should see low 12's high 11's or better, no problem. It's all in the combination.

Yeah, I figured the cam would be junk for a setup like that. I just got the whole top end for a steal on ebay so i figured i might as well use it. What would you recommend for a cam? Custom ground or just a higher stage?

Theres also that part of me that just wants to keep the stock internals and run nitrous on that top end until i have enough to do the turbo kit all at once. How much do you think i could safely run like that? More of an advantage? I mean it would be cool to run on all motor but this is just my weekend play toy so i'm not too too worried about it, but i'd still like to be able to be on the safe side and not have to worry that much. This seems like i'd be able to get the results i'd want at a cheaper rate. Just throwing some ideas out there and trying to make one stick.

I would go with the 347 with that top end so you have good power at all times. I would imagine you could still run less shot of nos to get you a little more HP and still stay within safe limits, but seriously how often do you get to use nos except at the track?

If you keep the block stock or just upgrade the internals you'll need more shot to reach the same goals and depending on how often you use the nos it could get to your pocket real fast.

I think a N/A 347 would be much safer and cheaper in the long run. If you don't plan to keep the car for a long time then I'd say stay stock and spray the crap out of it. Have your fun until it can't handle anymore.

[93hatch]

wana buy a nitrous cam ground for a 347 with tf 170s?

[FastStang91Lx]

^^^^ That wouldn't be a bad idea for him. Makes good power off the juice too.

[93hatch]

sucks I lost the dam cam card.... shit idles at 750 too

[BadBlackGT]

I'd love to stay N/A lol but I just want something fast without having to cost me a shitload of money. I keep thinking I could just run the 302ci with some boost and get there easier, but then I keep thinking if I ran a 347 would I be able to use any kind of FI on that because that seems like it'd make more.

How much could I make on a stock block stock internal top end 302 with the ideal amount of nitrous to still be safe?

Same question but with the 347 (assuming if everything was spot on), stock block forged internals.

[Stdyhand]

The 347 is going to give you more consistant at all times. You should be able to give it a small shot to gain more. If you don't always drive hard and you only want raw power from time to time I'd say stay stock and spray it heavy when you need it.

Whatever makes you happy in the long run and doesn't leave you with regrets is all that matters.

As I said I am a sucker for N/A. I like knowing I have that power there at all times. I don't have to worry about a bottle being low or with my bad luck exploding If I find myself in a position where I need good power right then all I have to do is put it to the floor and will hopefully get myself out of trouble...or maybe in trouble

Yeah, ideally i'd love to be all motor around 500 horses lol. But i've learned that cost SO much more. I've been looking at some vortech's on craigslist around here that i may end up purchasing too idk. This car is just going to be my track car and something to putt around in on the weekends so its not going to see much run time, but when it is... its going to be hard. I guess I could always run a 347, that trick flow kit with a better cam and some high compression pistons with better gas?

[BadBlackGT]

Theres always the 331 too
I hate having to make decisions like this lol\

would a 331 9:1 compression trick flow track heat intake and heads and and Anderson b 31 cam put me around 400rwhp? Open to suggestions.

But it'd probably be cheaper and more durable to just go buy a 351w, rebuild kit, and slap my top end kit on it and spray it huh?

my car makes 388 on small parts

347 10.1-1
your heads mystery port
tfsr lower box upper
custom cam from a diff motor
small exhaust

well i've already got the tfs top end. I'm not wanting to sell all of it unless i absolutely have to. I'd like to just be able to run mid to low 12's. Would i be better off running a stroker motor with this top end and a different cam or a 302 with this top end and some boost? Like I said i'll be running a c4 with the supporting gears in the rear. Its a drag car.

people run 10's on a 302 with a turbo.. just saying

That was actually my original plan for the car. To put this top end and spray it until I got a turbo kit. I just want something that will make me feel like my 02 GT is slow as fuck. Well I already feel like that, but I want it to actually hold me back in the seat.
