Replacing the Speed Six with a V8

[timarrowsmith]

Has anyone considered or researched this?

Initial thoughts: Chevy small block V8, aiming for approx 400hp.

(and yes, my S6 is ****ed and I am just considering if it is feasible to nail something else in for the same ££ as a rebuild...)

[unrepentant]

:yawn:

Not again.

[timarrowsmith]

dead helpful that, thanks a lot. must give you a big kick to be so condescending.

perhaps you can be more helpful next time.

Hi Tim,

I suggest you speak to Boosted LS1 his website is below if anyone can do it he is probably the man.

www.chevroletls1.com

Still shame to give up on the speed six some of us are trying to get the rebuild / repair costs down so it need not be such a disaster.

But I do understand your frustration

Hi Tim. Its been asked quite a few times hence the response. The chassis is designed for a straight 6 and is too narrow for a V8-even a small block. It would need serious and expensive work to wedge one in,although no doubt one day someone is going to try.

[timarrowsmith]

thanks for the helpful replies - OK so I need to explore a 6 pot going in then....

I thought that Mike Johnson had measured it and was waiting for a project car. Instruments, manifolds(esp around the steering column) and proximity of bulkhead are the main areas of concern AFAIK. Good luck with a chat to Boosted if you try. J

An M3 engine fits a cerb , wonder whether it would fit a tuscan.

It's also been asked by the same poster before. Three months ago!

Hence my response. :yawn:

[timarrowsmith]

And why do you think I am asking? Just to annoy everyone?? or because maybe I'm a bit thick??

No; I had a computer problem and haven't been able to find any of the replies I received, nor did I get any of the notifications usual with this site.

So, next time you waste a few precious moments of your life typing something that will waste a few moments of mine (and everyone else who has the misfortune to stumble across your "contribution" (and I use the term with some sarcasm, in case you werre wondering), perhaps you ought to engage your brain and remember why you are on here: it is a forum, a virtual space for the exchange of information, ideas and opinions. Some people even forge lasting friendships on forums like this.

Seeing as I've been advised to come on here by TVR to research this issue (with a warning that I might encounter the odd a***hole - what foresight...), I was glad to see that some kind people have been able to point me in the right direction.

You, however, Mr Unrepentant, are seemingly here to post irrelevant comments and to provide no assistance at all.

Why are you here? Nothing intelligent to contribute? Maybe you're in the wrong place.

[rev-erend]

It would also be worth talking to JELLISON who has made a superb job of putting a SBC into a Chim.. and LS1 as others have said..

[timarrowsmith]

thanks rev - just checked out his profile - veyr interesting!

Many on here have created spectacular beasts and will, I am sure be more than happy to help you out.

Ah personal insults. Excellent. The last refuge of the intellectually challenged.

[timarrowsmith]

Thanks for the bhpworld link, that makes very interesting reading. I've already had a chat with a couple of experienced engine builders / race prep guys and the possibilities are interesting.

Alternatively I might just swallow the cost for a rebuild and then hang around on here and make stupid, unimaginative comments to people with genuine questions.

[timarrowsmith]

oh and well done for progressing to words with 3 syllables....

[Steve_T]

Tim it's certainly worthing considering the Autocraft rebuild of your engine against a V8 install. It's worth bearing in mind that Jon sunk an awful lot of personal time into the conversion. If you had to pay for this as well, you may be looking at several thousand more than Jon paid, assuming an LS will fit of course.

On the topic of non TVR S6 rebuilds, check out profiles and postings of

red rose
and
J.T.

as they are the first people having work done by Autocraft.

[timarrowsmith]

Thanks chaps, all helpful stuff. I've followed the progress of the autocraft idea from afar and have always been keen to see the longevity of the conversion. In theory it does sound rather a good solution, albeit a more expensive one.

[Steve_T]

I take your point re more expense, but if it proves more durable, then it ought to be less expensive per mile in time. A cheaper rebuild may turn out to be false economy (hence your V8 questions I guess).

Good luck whatever you choose,

Steve.
