GT-40P Headers

[Mercracer]

I posted a couple of pictures of FRPP headers and a couple of MAC shorties to illustrate why FRPP headers are worth the money.

My BBKs look very similar...

Can you use a socket on all of the bolts with your BBK headers?

Yes, BBK makes a set of headers that were specificaly designed to work on the GT40P heads, they are the only other major brand that makes them.

I didn't ask if they made them..........I asked if you can get a socket on all of the bolts. The old FRPP SS headers fit great on everything but P heads and they didn't need much welding to be modded for P heads. Although they were nice headers, you could not get a socket on anywhere near all of the bolts. The current FRPP SS headers fit all heads better than the originals and have plenty of room for all or nearly all of the bolts to be removed/installed with a socket.

Gotta love those autolite coppers

[mrltd]

Almost all of them. I would have liked to get the FRPP headers, but I didn't want to spend over a grand on my exhaust system again.


In fact, I think all but one on the driver side. #6 IIRC.

Im guessing those are made for application in mustangs???

When I think of GT-40 headders I always picture those wierd ones that go in explorers...

GT40P headers are correct for mustang and our cars. But the primaries come out farther from the block so as to accomidate for the spark plug location on the P heads.

Will I still need 90* plug boots with the FRPP headers? Ordering tonight, so please answer soon.

The ones in the pictures are standard Autolite wires. They work fine. No special wires needed. Wire clips are a must have with any header. If a wire touches a hot header, you are minus one wire.

How do you like the performance of teh Autolites?

Considering I'm running "stock" equipment, I'm thinking cheapo wires will do fine, as long as I stuff the ends with dielectric grease.

11.36 at 120mph......they seem fine.
