looking at buying a set of headers for my 70 with a 302..car has manual steering and a t-5 with hydraulic conversion...looking at the hooker 6901hkr from summit and also the hedman 88300...im even considering the summit brand....is anyone running any of these? if so how did they fit?..im prepared to make modifiications to the headers but would prefer not to..
The Hooker 6901 fit my Blue Grabber with a 289 with no issues, other than it being an automatic trans. and power steering, you should have little to no problems with them in your setup.
Hi I run the 6901's with manual steering and a Mcleod bell housing with a top loader 4 speed at the rear. They are very tight going in from underneath and you have to unbolt one mount at a time and lift the engine up but once in its all good. I had a slightly modify the bell housing flange to clear but the Mcleod housing is quite large, I didn't have to modify the headers at all. One thing I did have to do was shave the top of some of the mounting bolts for clearance against the pipe. Drivers side has to be removed or released to change the spark plugs but this is the only bad part. I hope this helps. Regards Phil
i have 6901 with a hydraulic clutch t5 with manual steering. the only problem i had was the pitman arm for manual steering hits one of the header tubes during a left turn. it put a dent in the header tube. on mashoris car with the same set up, the pitman arm hit header tube a lot more and limited his turn radius significantly.
Ive used the 1-1/2" and the 1-5/8" Hedman headers. Both fit flawlessly without hitting anything or needing any clearancing. I havent heard of anybody needing to do anything to the Hedman headers to make them fit. But quite often you hear the Hooker's need some clearancing here and there.
That's what I noticed with my 6901's. I haven driven it yet but I'm curious how much my turning is going to be limited.
I have been wondering, the steering issue some folks seem to have with the hooker headers getting in the way of the pitman arm, some have the problem and some don't, I am just wondering if it might be the way the front end is setup/aligned like maybe adjusted to one side a bit more than the other, I have had the issue on one car but not on the other myself.....
One was manual, and the other power steering, the power steering had no problem hitting the pitman arm but it did have a drop bracket on it for the cylinder, My green grabber I have now severely limits my turning radius to the left, just seems to me it could be adjusted out a bit and help it some.
I put hedman 1 5/8 headers didn't scratch or ding them anywhere plugs are fairly easy to change on my brown maverick
my car came with headman headers. they had oval ports. the ovals over hang the corners of the rectangle ports of my heads and a few ports would not seal. those were on stock exhaust ports. my new motor had bigger ports and would have made the problem worse. that is why i went with the hooker headers.
'70 with a T5 and manual steering here, no problems with the 6901's with the exception that I'm running head studs instead of bolts and had to clearance the flanges some.
Ok I'm going to try and tack some questions on here. I'm looking at the 6901's and the doug thorleys because people keep saying they fit the best. I was planning on a 2.5" exhaust system. Both the 6901s and the doug thorleys say they have a 3" collector. Does that mean I should plan for a 3" exhaust system? OR is a reducer in the works. I'm planning on running this with my stock engine for at least another year, then I'm upgrading the motor. (either rebuild mine, put in a 302 HO, or buy a crate... but no more than 350HP no matter which way I go) Also this left turn issue with manual steering is interesting. Read a lot of threads on this forum and never ran across that. How bad is it? My comet is my DD, will I get tired of it quickly. I wanted to run full length headers... (for no good reason.) I'm not too worried about the install, I've got help from more experienced people than me. I am worried about getting it all right the first time.
