88 Tbird regular 5.0 questions

My dad and I are checking out the 5.0 HO conversion site (http://www.coolcats.net/tech/advanced/ho_conversion.html) and it mentioned getting a stock HO camshaft, which is a roller cam.  We were wondering if the camshaft in the regular stock 5.0 is a roller cam too because if it isnt, we may need fingers to hold the lifters on.  Also, does the stock block have the bosses to bolt the fingers to?  Thanks for your time.

I believe all 86 and newer blocks are rollers. 87 and 88 for sure. The Mustang cam will work in your block with your stock lifters, pushrods and rockers

Ok, thanks for the info!  Will we need fingers for the lifters or are they rollers already?

I honestly dont think you could exceed the cost of a new car buy installing new *stock* parts everywhere in your coug our tbird. Its just plain impossible. You could revamp the entire drivetrain/engine/suspenstion and still come out ahead.

Yeah, we're going to get all the pieces on that list before we do the conversion.  Might as well do it right the first time :) .

Good, good.  Well, it's time to check the first part off the list of conversion parts cause we just got an HO upper intake on ebay for $5.50 (plus shipping, unfortunately haha).  1 part down...lots to go...

86-88's were all rollers stock. Everything before that was flat tappet.

Generally...yes. 1985 was the first year for a roller block in a Mustang. All the books list 1986 as the first year for other Fords (Cougar, Thunderbird, Grand Marquis, etc.). But it seems the roller block was a running change for the 1986 model year with the Cougars & T-Birds. I've talked to a couple of people that cracked open their stock early-'86 engines and found they still had solid lifters. I don't think they were all roller until sometime after November 1985. All of my '86 cars have been late builds (March, June) so they definitely had roller blocks.

Yep all late 86-88 Tbird/Cougar 5.0 SO were rollers. There has been fights on panther boards about when Crown Vics/Grand Marquis got roller blocks but the agreement has been late 86 model year and up 5.0 SO were all roller. Now I don't think the 5.0 SO had a double roller timing chain like the HO though but I could be wrong....

You're right---they were single roller timing chains. Also, the 1986 timing chain sprockets were steel, but the 1987-88's were plastic. Yep...plastic. Thanks for the weight savings, Ford! ;)
