Stroker kit or 347 block?

[Nosty94]

Hey guys. I was wondering if anybody who's done this before could chime in and steer me in the right direction. I have a 94 GT with about 80k miles on it. I did the Trick Flow top end kit last year but now I'm thinking I want some more power. I don't have a budget planned out yet but I'd like to go an economical route. So I would like to keep my top end and upgrade to a bigger block that will still accept my intake manifolds and maybe the heads too. Should I
A. Get a 347 stroker kit for my current block?
B. Buy a 347 block already set up. If I go in this direction, where do I go to get it?
Any help would be much appreciated guys. Thanks!

 

[Nosty94]

Sorry. Forgot to ask. Anybody who has done either one. How much would I be expecting to spend on either one? Thanks again

The TFS heads that come with that setup may be too small for the 347... You can get a bare block from Summit for 700 that already has all the machine work done for the 347 internals to go in. You would just have to check around on how much it would be to get your block ready for the stroker kit. The Summit block sounds like a good deal though.

So if I got a block from Summit what else would I need? Aside from if I needed bigger heads. Would I be able to find a package that would have all the internals needed for a 347?

To be quite honest with you if your on a budget and you already have the heads and upper intake stuff, get the short block from latemoderestoration.com for $700 and slap your stuff on it and rock it out for the summer. You can beat the piss out of it for the $. Then you dont have to worry about all the monkey business of putting a motor together. Its July already. 3 more months to snow!!! FTW!!

Depends how much more power you want? Just going from a 302 to a 347 with the same parts is not going to gain you more than 40hp at most I'd guess. If you EVER plan on a SC get an aftermarket block. Don't do it 3-4 times. Drive what you have until you can get a nice Boss or Dart block stroker if you want to SC or Turbo later. Or really just add a SC to what you have now and you will be close to over over 500rwhp. That is the biggest gain for the $$ really.

The TFS heads are great for a 347, but I'd want a different cam and possibly intake as well depending which one you have now.

 

[Nosty94]

Right now I have the street intake from TFS. I was going to think about a supercharger but I didn't think it would be a good idea to SC a block with 80k miles on it? Or am I wrong? I really like the simplicity of the KB superchargers but I already did the upper and lower intakes unless I could sell those. What superchargers do you guys like?

I have an s trim. Alot of guys run these with very good results. ive seen 750rwhp from an old s trim with a dart block. You can find them a dime a dozen for around 1500 for the whole kit. Find a used on still on a car that you can hear running.

It was cheaper for me to go with a new shortblock with good internals than it was to have a new motor built. I spent around $2800 on my 347 and I ended up getting different heads and a different cam.

Agree, supercharger most power for the money. Vortech strim is a solid kit. As was sItated earlier, close to 500rwhp with what you already have. And I just so happen to know where you can get a good deal on one with an aftercooler, a must for reliable/consistent forced induction power. 80k miles? No big deal. Do a compression test and see where you're at.

80K miles is not even broke in yet LOL. I sc'ed one with well over a 100K and it is still going with close to 180k haha. Superchargers don't hurt motors, stupid owners do LOL. I'd do a compression test plus maybe even a leakdown test as sometimes weak rings will not show issues until boost is added to the mix. Seen this with a friends car.

Depending on the year of the car, a Vortech S,Sc, Si, Sci, etc works great as do the Paxton Novi units like the 1000, 1220, 2000, 2200. I have installed or owned Vortech, Paxton, ProCharger, Powerdyne, and Kenne Bell superchargers.

Nicely put!!!

Hahaha! I helped a guy install a Kenne Bell way back on his 88 GT and I told him "take it easy and listen for detonation, if you get an let out immediately!". He took off down the road WOT and it sounded like he was towing a 55 gallon drum of marbles. I NEVER have heard a car spark knock so ba in my life. He turns around and beats on it on the way back, pulls in the garage and coolant is blasting out the overflow. DUUUUHHHH. THEN blamed the supercharger and ME.:smash:

I can tell you from experience. Do not buy a storker kit and then use your block. Just buy a 347 short block from a good company. I bought a 331 Stoker kit and had my block done. Not only do they have to tear down your motor Which is a fee to do. But then they have to do all the machine work to the block as well. Which all adds up. It cost me thousands more then if I was to have just bought a 331 short block. Plus the down time you will have on your car. The Machine shop I used had the motor for months before they got it done. When you order a new motor you just get it delivered and then swap it out and down time is weekend.

Now My motor now is a 347 (with a racing block) with the trick flow Top end kit. I change the intake, and the heads have never been ported. Just the way they came out of the box. I also have the stage 1 cam, Push rods and rocker arms. I also have a Hp performance Stage 2 Turbo kit on my car. Which is only a 66mm turbo. The car has gone a best of 9.39 @ 140+ mph

I had a Foxlake built 331 stroker and it was a nice engine. ZERO blowby even with a decent amount of boost. I sold it to a friend, had a TFS Stage 1 and ported TFS heads along with a Holley intake. I should have kept it all really but needed the $$ at the time.

 

[Nosty94]

Thanks for all the suggestions guys! I think what I'm going to do is get a new 347 block and switch over my top end. If need be I will get the new heads or have mine ported. Now all I need is a recommendation on where to order a block with all internals ready to go so when it arrives I just swap it.

 

[dsblk93gt]

I liked my Foxlake built motor but a lot of guys like fordstrokers.com

Fordstrokers very reputable on the Corral and great customer service. I have spent a lot of time on the phone discussing engine combinations with Woody . . .very helpful and knows his stuff (from what I can tell, LOL). ONly issue is that its a +5month wait . . . .I am anxiously awaiting my new motor.

As an FYI, I was on their website yesterday and Fordstrokers shortblocks are currently 4% discounted.
