8.1 litres = approx 490 cu "
How would you go if you wanted to upgrade your coil(s) in one of those things? That's gotta inflict some nasty pain in the wallet region for sure.;eek

Any info on what block he used? I am presuming the motor came from something older than the car it went into or it came from a truck.
C5 and even C5R blocks can't be taken out that far to my knowledge.

Diagnosing an ignition problem could be more fun than normal too. ;eek Not that I'd turn down a C5 if one was offered to me. :)

The more the merrier. ;);35

VO,
Apparently, the 8.1L translates to a 496CID engine. Its the truck engine that is
used in the 3/4T truck lines.
She puts out 340Hp and 475FT/Lbs of torque which I thought was a little low actually. There's also a marine verson that's rated at 375hp.
I dare say that this would very well be the ONLY huge block C5 around.
ps: 7cvt-> r those red x's attempts to post smilies ... ?
-
BAH! What these c5's need is a good ol RED motor! Gimme a Holden 253 any day
:P
-
mate, you could've picked any other motor but a 253 ??? I used to blow those of in a baby 6 Cortina ....
-
What red x's?? VO can see 'em!
-
-
betcha a 4X VO see's Red X's
-
Geeze now I'm gettin' red x's - what's with this place? don't get too excited - it was only a drooling Homer.
-
does that mean I don't get my 4x ?

No I can't... ;30;--

NOW do I get my 4x .. ?

Things have changed a little now. I pasted the address of 77CVT's link into a new window and got the pic.
BTW, when I couldn't get it yesterday I checked the links properties and had a pretty good idea of what it would have been. Turns out I was right. :22

;30 Arrgh, right after I made the last post I noticed the link now works...;30;30;30;30;30

Thanks for the info.
Assuming all that info is spot on and the car in question is a Z06, the car has dropped a minimum of 45hp but picked up about 90 FT/LB of torque (based on a 2001 (first year) Z06).
I admire and respect the work and ingenuity with the swap but if it were my car I would have played with some bolt ons or done the heads and cam. Then again, it's not my car. Just my opinion.
Definitely wins bragging rights though, I bet he's got the biggest cubed C5 on his block. ;35
-
VO.....GREG morris from corvette conversion has done the sums, the measurements and knows the right 500cube motor and harness that will fit in a C4............now that'd be a REAL GUTTER SLAPPER LOL :);)
-
VO, the authenticity is looking a little dubious now as why would anyone want to drop 45 horses ? Perhaps it wasn't a Z06. Whilst on the subject of dropping power like this, I noticed in the current Unique Cars a Victorian vette for sale that reads "used to be a big block now a 350cid" .... I'm not being critical but why would anyone want to change a big block 4 speed to a small block 4 speed ?

Just guessing but I would assume one of two things - number one being most likely:
1. The big block motor died and it was more economical to install a replacement small black than repair/replace the big block.
2. The owner thought the big block was too heavy, thirsty, more than they needed/whatever and dropped in the small block instead.
Thats my theory, the current owner could probably set the story straight on that one.
-
yeah, No 1 had crossed my mind but the drop in power AND moving away from the original design would force me to put off restoration until I could afford it. I dunno there's probably a good reason and maybe a previous owner did it.
I'm feeling adventurous, I'm gonna ring him and ask him .... he's probably a member of the Vic Corvette club so wouldn't mind a chat about his vette.
