there is an ls swapped c4 for sale for about 13k which is a pretty sweet deal

I'd come up with a few k more and just buy another ZR-1 myself

I want to swap the LS into my old 68. But if I do I know I won't sell it!!

Also want to swap the Saturn Sky like Mallet did with a turbo LS

I also have a Porsche 944 turbo.

But the LSV will stay where it is. IMHO, the ultimate "swap" for a c4 IS the ZR-1

It certainly looks very nice. First things first, putting the FR-S up for sale, that will happen in a week or so.

Might also do an after market seat, it looks like there's quite a few options available to lower the seat 2 to 2.5 inches.

2022 C4 of the Year Finalist - Modified

Default

Years ago I put a V8 and a 4-speed in a 64 Nova I had and I wanted to use the short Hurst shifter but it came too close to the seat so I made some seat extensions out of some 6061 aluminum and it did the trick. Lowering the seat in a Corvette would be no different. The seat in a ZR-1 is bolted to the seat track,bolt the bracket to the floor and then bolt the seat to the bracket and in the process pick up 2-3 inches of headroom.

Z51Jeff, I was talking with a buddy of mine yesterday who's restoring a C4, he said pulling the seats is pretty easy and that there are plenty of aftermarket seat MFGs that offer rails and everything. Seems like a good way to go TBH.

michael jordan had a 93 zr1 that they modified to "slam the seats" and lower them as much as possible

much over 6 6 you may be a bit too big and need to take the top off

Alright, quick update, you guys were dead on re: cramming my *** in the seat. I sat in my buddies 85 today and I need to drop 2inches + on seat height.

I've tried to find decent seats, Summit doesn't seem to have anything, or their search function is broken, everything is C5, C6 and C7.

Any seat recommendations for the C4 that I can start looking at? The FR-S is likely to go up for sale next week and then its game on to find another car.

good point
Are they worse than the C5s inside for room?
Yes
Theres no way to judge until you sit on a Z not an early one as the consoles and dashes are different
A good upholstery guy can modify your seat

Far as cams etc you dont need them
port the intake and injector housings, stick headers and a nice 2.5" exh 4.10 gears thats about as good as its going to get cost wise
Should have an honest low 12 sec car.

Value on a bigger LT5 dont worry about all that #s stuff it doesnt lower value at ALL. Guys pay huge money to do these
(its either an LT5 or it isnt)

Couple 415s and a 440? on here they make crazy power. If you can buy one done youre ahead of the game youll never have a problem reselling it

These arent C1-2s where guys go gaga and fret over value. They were meant to be driven hard, and often so do it

Why would a ZR1 be a money pit?

I hadn't been in a C4 in a number of years until yesterday I forgot how much smaller they were inside. It's a tight fit for sure, definitely need aftermarket seats to make it work for me to drive and especially to spend any time on a track.

I could go back to the C5 Z06 or a C6 Grand Sport those are really the only two "modern" corvettes that have some major appeal to me. Removable hard top sure would be handy though...

one of our FBI guys here in Chicagoland just announced availability of a 391-396 CID package for the LT5. 600+ at the crank using stock crank and rods I believe. About a 15k package includes porting and cams.

480+ crank hp is standard issue on an LT5 w just ported top end and headers. You’ll have an additional 1000+ rpm for power peak. Oh and it will still idle like stock.

Here is a
, puts down 432 at the wheels: Stock cams, stock TB, LT headers and a stock idle. It has surprised "a few" who mistook it for a stock, base C4 and were chagrined to say the least.

It has run in the low 12s at 121 mph in the 1/4, and 144.25 in the half mile. At 50 mph shifting from 5th into 2nd and standing on to 90 mph will snap your head back and slam you into the seat and again when you shift into 3rd and when you top out at around 7200 and grab 4th...There just isn't too many that will be scoffing at C4s after that.

And, the LT5 just takes it all in stride, and keeps on coming back, licking its chops for more! And porting is just the beginning! Add cams and closed deck, and low 10s are common place here in FBI land.

ZR-1s/LT5s are amazing animals - especially when it is ported/tuned. Quietly maneuvering in traffic with the AC on one minute, and screaming like a banshee to 7200 rpm the next and back, w/o a whimper. There's NOTHING like um, especially with a touch of porting (oh, what fun was left on the table in these cars)!

What is "FBI" and that car is sick.

I've got an inquiry into Carbeau to find out what their seat options provide in terms of adjustability and how much lower they are vs stock seats.

You can have an LS whatever,or you can have a ZR-1. The choice is pretty clear.

Fast Boys of Illinois I believe. I don't think your going to find what your looking for in an aftermarket seat. If Michael Jordan can fit in one anybody can. What you can do is try and find a seat track out of a car and measure the thing. The only issue I would have with doing away with the stock seat track is you have a lot of adjustments there. If I were in the market for a ZR-1,really wanted one and I was in your position I'd buy the car and make it work.

MJ probably had something done with the seat.

I can't crane my neck or tilt my head to the side while driving, it's not really comfortable and don't have a shot at getting a helmet on. I've got about an inch on MJ by the way

I agree with you regarding seat adjustments, if I pull the stock seat out I'd keep it for the next owner, I'd wrap it in plastic and put it in my conditioned attic.

I don't really want to give up on the C4 yet, if I have to then I will...what makes you think aftermarket seats won't work?

Its actually Fast BoyZ of IllinoiZ. Bit of a play on the Z moniker.

An aftermarket seat will come with seat tracks that will put you back at square one.
