engine size in 1987 nhra pro stock for the bbf guys!

Post  nitrous.f on December 16th 2015, 10:51 pm

was just on youtube looking at some old 1987 nhra national events when bob glidden was running and was wondering what was the spec on those engines for the bbf guys and what heads were they running! loved to watch the fords in pro stock dominate the class back then! don't watch it for no other cars but the fords!

Around that time the NHRA limit was 500", and I think the IHRA had no cubic inch limit (IIRC the IHRA limit later became 815", and then something like 840"). The NHRA 500" engines usually used a short deck block. In NHRA trim Bob/his sons did eventually try the wedge heads. This was because he had reached the Hemi head's limit on compression numbers, and the GM guys with wedge heads/more compression were starting to catch & pass him.

And IIRC in IHRA trim Bob only used the Hemi heads, (and not the wedge heads) because getting bigger compression numbers wasn't as much a problem with the larger IHRA engines.

In 1987, isn't that where they had all of those different weight factors ...?
Probably a Cleveland engine in a 4 door Maverick or Fairmont or something like that.

The NHRA 500" max rule started in 1982, so no Clevelands or weight break rules in NHRA Pro Stock in 1987. And IIRC the 5 year body rule was in effect in '87 so the Maverick body wouldn't have been legal in 1987, but the Fairmont body would have been legal until 1988.

how interesting! what kind of et,s were they running with those heads in the nhra 500" class Question just looking back at the days when guys really wrenched on there rides. I think they were around 2300-2500lb, could be wrong! Very Happy

When the NHRA 500" rule went into effect it also mandated a 2350lb minimum weight.

Never where from my understanding, the hemi heads would kill them.

The Aheads wouldn't fall out of a tree for nhra pro stock,The bastard a460 (style) head was better.
Frank I. ran those a few times ,But the Boss was best. In ihra the fastest about this time (87) was a 6xx ci (BOSS) engine. Bob Gliddens, he went 7.00 and 199 with it.

This was his last pass in IHRA TRIM

A couple years ago, my neighbor freshened up the motor for the current owner of one of those cars. I don't know who the owner is, but it was cool to check out the car.

They are claiming 704HP and 9.90's in the article I linked. The info I have was 648 and mid 10's from another article in 1987. You can scan the link with the magnification feature and read most of it if you want.

A460 heads were never approved for use in Pro Stock Glidden tried E460 heads but the engines never made the power that the B 441 Hemi made.

Sorry A441 is right. The C followed by the E and both were a major amount of work for Bob.
