My new project car: 1990 Mustang GT - Page 3

Silverstar · September 26th, 2007, 08:00 PM

Aye it's a 2.5". I was debating getting new headers that were 3" since I thought the system was completely ruined when I got it, but completely fine now.

Demon_X · September 27th, 2007, 06:12 AM

so this gonna be a drag car?

or you gonna do a road course soon?

Silverstar · September 27th, 2007, 06:28 AM

I'm almost dead set on it being a joy/drag car, being as it's not a car favored around tracks. But I'm not going all out with a roll cage and drag racing suspension, I'll be restoring the body/interior over the winter. Trying to make it fast enough to bracket race...and still have a functional street car.

If anything I'll take my STI to another track day next spring, haven't been to one since Willow Springs back when I was still in California.

*UPDATE*
After the last track day coming this weekend, I'll be taking the motor out to prepare it for a stroker kit. images/smilies/biggrin.gif

331 or 347?

Silverstar · September 27th, 2007, 06:47 PM

My heart says 347, but I'm still not sure. I've also been scowering for some 351W blocks to 396 or 408 it out, but I'm not having much luck locally finding a rotating assembly or even just the block.

I'm going to take it to an engine shop to have them take a look and decide what's the best for my app., and I'm going to put their name behind it. Going to get it right the first time.

CraigB · September 27th, 2007, 10:45 PM

I was looking between the 331, 347, 351, etc. and decided that the 331 was probably the best. The 351 will require new headers, oil pan, intake, etc. The 347 has the oil burning problem since the oil ring is in the middle of where the wrist pin goes (they are a few special kits that don't have this problem though). The 331 is middle of the road. Though just a nice set of heads will make the ole' 302 work well. A buddy of mine has a 306 with stock ported heads (either E7s or DO0Es I think) and a stock bottom end and has run low 10s on the spray and it runs mid 11s off the bottle...

Silverstar · September 28th, 2007, 01:41 AM

I just got off the phone with my cousin (has a '89 GT, influenced me to get one images/smilies/biggrin.gif

), and he was also saying that 331 sounds pretty middle of the road and decent, looks like both of you are leaning in the right direction for me images/smilies/biggrin.gif

I was looking here at the combos. With the top end mods I have currently, and some headwork along with this stroker kit, I'm hoping I can hit the low 12's.

Silverstar · October 2nd, 2007, 06:14 PM

Well, still planning on getting a stroker kit...but with this instead:

351W images/smilies/biggrin.gif

Got the complete engine for $250(EFI), stripped it down to the block and is being boiled/magnafluxed as I'm posting this. But of course going to make sure that the block is still strong before I go pulling the 302 out images/smilies/biggrin.gif

CraigB · October 3rd, 2007, 12:59 AM

Roller block?

Silverstar · October 3rd, 2007, 01:58 AM

Solid

. Had to bang out some of the lifters out with a flathead screwdriver images/smilies/biggrin.gif

. Not sure yet whether or not to switch to roller, as I know it needs to be a custom grind.

Any suggestions Craig?

CraigB · October 3rd, 2007, 11:51 PM

Cam depends a lot on your heads, what are you planning there?

Silverstar · October 3rd, 2007, 11:58 PM

I'm really not sure. I guess I would probably go with the heads on the 302 right now, they flow about the same as aftermarket 351 heads from what I've been told. If not, probably these if the ported ones fit the 351, twisted wedge version.

CraigB · October 4th, 2007, 03:30 AM

What do you have now, E7s? They flow about as much as ported '69-'70 351 heads...

what are you nuts? 2.5 is already nudging on too big. Trust me, you don't want to go larger then 2.5 on a car like that, it will sound pretty crap at anything besides low-rpms

Silverstar · October 4th, 2007, 05:38 AM

I think the problem was finding myself a 2.5" kit for a decent price. A lot of the Flowmaster systems were 3", which was what I was wanting. Your right though, I got to hear a Mustang at the track that went from my size to the Flowmaster thunder 3"...just didn't sound right.

But with the 351W, I think a lot of the full-length headers are 3" at the collectors.

Silverstar · October 16th, 2007, 07:11 AM

Small update, 351W is being .030" overbored as of today. Leaning towards a 383 stroker kit, took the pricing in to the engine shop this morning images/smilies/biggrin.gif

Ottobon · October 16th, 2007, 07:19 AM

Nice to hear!

On a side note, i would atleast try the car on a track, my friend with a foxbody rather enjoys his car in such ways, and his beefy 5.0 vs. my tiny old MR2 was actually a really fun battle at grattan last year. Too bad my MR2 turned into a ball of rust and his loose trans mount combined with his quick-shifts ruined what was left of the 5.0s sychros.

As a perfect parallel to our cars demise the economy in Michigan is now at a all time suck.

Silverstar · October 16th, 2007, 06:30 PM

You know, I must just give it a try images/smilies/biggrin.gif

. I am debating going next year w/ both of my cars. It'll be the Mustang...which will have too much power for it's own good, but I am ordering a lot of stiffening mods for it. And then the STI to give it some small course fun, haven't been on a track day with it since Willow Springs!

It's just a problem that the chapter of SCCA (which is the only group I can find to race with), is out of Des Moines...+200 miles round trip. But they do come to Waterloo which is a lot closer.

CraigB · October 17th, 2007, 01:13 AM

A friend of mine had a 392 with Canfield heads, ran a 10.30 in a caged notchback...

Silverstar · October 17th, 2007, 04:53 AM

I'm still up in the air at the moment, even though I'm thinking 383. Is a 392 a slightly smaller bore from the 393? 10.30 is an awesome time, I'm hoping to get into the low 12's if any, really being conservative images/smilies/biggrin.gif

. I'm nervous that I'll break something come spring images/smilies/biggrin.gif

The questing my cousin and I were think about is consistency. I guess the trans shop downtown has a C-6 sitting around, should we take it? The guy was saying he can build it to be rock solid. But it's yet to be seen I guess, we still have to transplant things from the 302, and then tear apart the drivetrain next month.
