I've got 2000 GT and I have been thinking about putting a 5.4 SOHC in it - the question is whether or not it is worth it - I've found that a 4.6 SOHC weighs in at 500lbs and a 5.4 SOHC is a 525 - is the extra displacement worth the swap?

just for the heads up i heard an ls7 fits nicely in the engine bay, heads flow like niagra falls, and with a nice cam will pull harder then a kb cobra on the top end...ad some spray and check your pants

na i'll be honest its not worth it. You will se a 5 or 6 rwhp from the swap and about an ok amount of tq picked up, but thats it. I've done a 2v and the main thing is power to weight ratio. the added hp and tq will ultimately be offset by the extra weight.

That just doesnt seem worth it - I was reading a couple of accounts and they made it sound like the cat's pajamas. An LS7 would be sweet - dont those cost a ton??

It will be costly, my buddy Jason did it in his 03 cobra and he had PSR put it together. Has a single turbo, ditched the 6 speed and did a 4k dollar lentech 4r70w with a trans brake.

I think that an LS7 would cost a ton - unless a ZO7 crashed through my living room. But is the concensus not to do a 5.4?

In n/a form its not really worth the effort. BUT chuck one of these at it and it opens up a whole new world

So its worth it if I'm going to be putting boost through the engine? Sounds good

Well a fox body with some traction stuff and a ROCK STOCK Lightning motor went mid 10's... I think you would do ok

Ok - that seals it - I'll just have to be a little slower until I can put some boost to her

I think it's a marine engine hemi. I found the pic a while back and just saved it but I just searched "twin supercharged marine engine (http://www.whipplesuperchargers.com/content.asp?pageID=72)" and found a link.
