Interesting II...(Sorry Paul)

Back to the original topic-

How do you feel about the LT5 not having caps for camshaft journals and having to throw away the head/cover if that ever is out of spec? Is there anything to be done about that?

lots of complexity for 200 hp.

i flush the cooling system every year so here's hoping she makes it for a while

It was actually a good experiance for me doing this engine in the fact it heightened my appreciation, which was already quite high, for the original LT-5 design in it's era.

There's always reasons for seemingly odd compromises The 4 cam mod motor did duty in both RWD and FWD platforms. This meant some design decisions did not go the way we'd all want.

For those that see similarity between 4V Ford and LT-5, before jumping to conclusions you should look closely at the Ford 3.0L SHO motor, which shows more of the lineage and dates to late 88 introduction.

Now that I think about it, I have collected the whole set:
- 93 SHO
- 97 Continental (4v transverse FWD)
- 99 Cobra
- and of course my wife is still letting me campaign her 91 LT-5

I've always figured Ford missed the market some when they reduced displacement while GM continued to increase it, although they should have been right. As an old Mustang guy I was really glad for the tech they brought forth and man the 03/04 Cobra answered for a lot.

Cheers,

I was thinking something similar...Lots of complexity for 500-700HP, for my liking. Sure 'Lots' of them out there though.....

Wouldn't catch me throwing anything like that away. Shouldn't be a huge deal to repair, these days. Never done one, but can't image I don't have a contact that couldn't make it happen....

I agree 100%. Almost anything can be repaired these days.
