Hi guys, I;m going to order a set of Edelbrock performer series heads for my 1990 Bronco (5.8L) Edelbrock stated that the cylinder head only accepts 1982-1995 5.0L V8 Pedestal mount rocker arms and valve trains. My question is, are pushrods part of the valve train??

Also I understand that my truck uses a hydraulic cam. Does it use roller lifters?? I really appreciate all of teh help!!

 

hey bronco351
your valve train consists of the camshaft the lifters the pushrods rocker arms and springs and retainers. oh yeah and the valves
i think but am not sure but 1985 86 mustang 302 ho engine was the only engine that came with roller tappets, but im not sure.

 

You have hydraulic lifters but I don't think the roller lifters were available at that time. Roller tappets on the rocker arms may have been standard but I can't find my cross reference book right now and don't have it committed to memory.

 

You can find more information in the appropriate engine forum. In your case probably the Cleveland forum.

 

The reason I asked this question is because I'm concerned about ordering the wrong part. I;m going to be ordering the Edelbrock peformer series heads for the 5.8/5.0 engines. Edelbrock states that the heads will only accept 1982-1995 5.0L V8 valvetrains. I didn't have a problem finding rocker arms. I'm using pedestal mount rocker-arms with a roller tip. The only pushrods I could fine (they have to be hardened) were for a 1985-1996 5.0L with stock hydraulic roller lifters. I don't want to order them unless I know they will fot my 1990 5.8L.

THe cam I went with comes with lifters but, it states that roller lifters are only provided with the cam if that is what came stock with the engine. So that's why I need to know if my truck has the roller lifters or not. Thanks a bunch for all yor help!! I never thought picking out push-rods would be so hard.

 

I dont know where your shoping but Summit Racing Equip. has an excelent tech depart. and Ive bout all my racing stuf thru them for years! you can get every thing you need there plus answers to you questions, I'm working on a Alum head 351W for my Bronco, but im going with AFR 185'S there bout $250.00 more but well worth it! IMOP if your gona spend the bucks for alum head, then go for the (roller cam) and (roller Rockers) it would be well worth it in the end. I like the Ford Racing B303 cam or the (Comp Cams) . Good luck. I would like to know how it turns out! DW

 

the 1990 5.8 came with standard hydraulic lifters and pedestal mount rockers. I know because I just rebuilt me abut 8 months ago. If your pushrods are from a 5.0l then they probably will not work. The 5.8 is a 5.0 with 1/2 inch taller decks so I am assuming the pushrods would also have to be 1/2 longer. Since you have to get a new set, then you are actually in very good shape. You can buy an adjustable lenght pushrod to determine exactly how long your puchrods need to be. Look at the specs for clearance and take the measurement. If you are going to have to choose between 2 different lengths go with the slightly longer pushrods. They make shim kits to space the rocker arms out to get the correct valve lash, but of course you can't bring the rocker arms any closer. Since you are switching to new heads, even if you had a set of stock pushrods for a 5.8 they may not be the right length for your heads. As for roller lifters and cam your block will have to be machined to accept them. Remember that your 5.8 is a speed density system and won't accept to large of a cam change without problems. I wish I would have gone with a ford cam now instead of aftermarket. The stock 5.8 cam actually has a decent duration with plenty of vacuum at idle. Plus the computer is made for it. Order a summit catalog, I know that they have pushrods that should work.

 

Clevelands were gone after 1974 in cars and in trucks.

Interestingly, the 351 Cleveland built such a strong performance reputation and market appeal that Ford referred to the 351M as a "351 Cleveland" in their own marketing literature for at least the first couple years after the 351M was introduced. Ultimately, this led to a lot of confusion, and even a mistaken belief among some pickup truck owners that their trucks had 351 Cleveland engines. In fact, the only trucks ever equipped with a 351 Cleveland engine by the factory were '70-'74 Rancheros, which shared the Torino's platform and powertrain options.
