351 in a T-Bird?
Reply #24 –
I couldn't even come close to finding a Lightning lower for a reasonable price, and when I did (3 times) all deals fell through because they sold to "local" guys.
I ended up porting the living sh*t out of the 5.8 truck lower and buying a BC Broncos adapter($100 shipped to me)to put a stock HO upper on...the 5.8 truck/van lower has a seriously short height...the upper intake is much lower than the lightning...I'm still antiting hood clearance issues. I wouldn't recommed this method if you're trying to build something really serious or if you don't have access to the necessary tools/knowledge to really hog one of those lower intakes out.
Also, if using the 5.8 truck/van lower, there is no provision for the PCV, so you'll have to use the passenger side stamped steel valve cover (with PCV hole) on the driver side to clear everything.
I plan on running my set-up with SD....if the vacuum signal is right (proper cam selection) it shouldn't have any major drivability issues. The super secret cam I bought for my 5.8 is a flat-tappet equivalent to the lightning cam...plus a little...it is specifically for SD.
I also plan to run all the stock 5.0 Bird accessory brackets on it, there will be no problem with the alt. bracket (although the truck/van bracket looks like it'll place the alternator lower), but I'll have to modify the PS/AC bracket to reach the water pump studs, it'll bolt to the head with no problem.
I've seen a lot of people spend $400+ on a set of fuel rails for 5.8's...you can just take a set of 5.0 rails and, using a razor blade, cut through the rubber outter hose and then the inner plastic hose and replace them with the proper 5/16" fuel injection hose available from any parts store...also, use high pressure hose clamps.
Good luck,
Don
