Read the moparts tech section, Hookers are definitely OUT, Both Thorley and hedman Elite have 1&3/4"primaries, engine builder (Dvorak)recommended 2', I could probably live with 1&7/8 if i could find them, don't really wanna pay 5-800for TTIs to use on my "Rat rod" SE chall...BTW this is for my "mild" 500" bulldog headed solid cam RB 4 spd DOT tires 3500lb car.

I am building a 505 stroker and every engine builder I talked with recommends 2" primary with 3.5" collecter. I think the hooker 5209s are the least expensive. I will be running 1 3/4" headers for now because I have firm feel long steering arms but everyone has told me that i will lose around 50hp.

I think it would be worth the money for 2" headers.

OK, RTSE...but rea d our tech section here on Moparts if you are going with any angle plug head...I found the return rates at Summit particularly interesting.
THX, C

Come on, gang...I KNOW a lot of you got Eddys, Indys, and Bulldogs...whatre y'all using?

I have 2" TTI's on my 446 with eddy heads....fit great. I'd use a 2" on a 500" motor.

The 2" Hookers CAN be made to work too....Unlawful had them on his challenger with eddy heads and no problems.

I tried the 1 7/8" Hooker supercomps and eddys and they burned boots constantly....I changed them out for the TTI's.

Thats all I know really....

yeah, youre probably right...aggravation IS costly.

I do think you could get away with the 2" supercomps...

I've heard the 1-7/8" "COMPS" (not supercomps) can be made to work...but I don't know that for sure. Those are only $170...

From what I have seen there is only one tube that has to be "loveingly massaged" on a set of Hooker 2" Super Comps with the angle plug heads. Contact Zippy, he has a set of 1 7/8" Hooker Comps on his Eddy headed Charger and i think he only had to mildly clearance one or two tubes for plug socket clearance. I have a set of 1 7/8" Super Comps for my Eddy headed 451 low deck and #2 tube is a nightmare, bashed the devil out of it to get plug boot clearance. #8 needed slight clearancing for the plug socket to go on. Everything else is good to go.

Yep. I have a set of 1 7/8 SuperComps on an Eddy headed 500 stroker and the inside curve of the number 2 tube has to be dented (hammered) in about 25% of it's diameter just to get the plug started into the head let alone put a boot on it. Just about every other plug is a PITA to install or remove and I used the Accel shorty's which are about 1/8" shorter. I have heard that the 2" SC's are better due to different tube positioning.

I use Hooker 2-1/8" with 4" collectors race adjustables, perfect for my 400 based 452 stroker. I use eddy heads, fit perfect.

OH is correct, with E heads and 1 and 7/8 Comps (not Super Comps)I had to very slightly ding 2 tubes on the passenger's side. No big deal, I've had the same plug wires since 2001 or so and have never burned a boot.

Will be switching to 2" Super Comps shortly, Looks like some mild dinging of #1 is all that will be needed.

i have e-heads on my 465 in a 73 charger.tti 2"fit well but anything less than WOT car was slower.it is heavy and not a lot of converter or gear(at the time).i have regular comp 1 7/8 hookers on there now.i had to clearance for the steering box and coupler(different clearance issues on 73-74).for more street than strip 1 7/8 would be fine.

The comp 1 7/8" work great on strokers if you replace the 3" collector with a 3 1/2", it's the collector that's the bottleneck mor than the primary diameter.

Yeah, but what about my Track dawg bulldogs, i reaal don't know if they actually are configured same as eddys...I suppose they SHOULD be...

I use TTI 2 1/8 Gotta let them 500's get rid of exhaust

I use 2" Hooker Supercomps on my 440/496 Edelbrock heads in my 71 Charger Superbee. I only had to ding a couple places for frame clearance and inner fender on the passenger side. I do have to use a motorcycle/snowmobile type sparkplug socket on #1 plug. You know, one of those thin sheetmetal stamped cheapies that come in a motorcycle tool kit....works great.

I ran the 5903's Hooker comps with some small dempling on the #8 tube due to angle plug clearance, the Bulldogs may fit betterm I was thinking they used stock eshaust location, where eddys are moved 3/8's or so. Also the header collector was tight near the driver side orsion bar, this was in a 69 B body with RB engine. spark plug changing sucked but you get faster after doing it a few times.

Results are in, 5309 2" SC's work with fewer modifications than 5903 comps. The previous owner had already put one small ding in #1 pipe, and that's all it took. Right bank is easy as pie, no mods needed. So...either one works fine with minor tweakage, but the 2" ones need less work.

So Zippy...#5309 2" SuperComps? Are these a "slip together" header , and will I have a "normal" collector to bolt up exhaust to? All things considered is this the best choice in your opinion for my app? Are the 1&7/8" Comps your second choice?
Thanks, Casey

BTT, Hello Zippy, Zippy???

Spoke to my "personal" Summit guy last night, he swears no such# as 5309 in Hooker catalog, says it must be 5209 = 2" super comp @419.00
The 1 7/8" are 199.00.Leaning towards these for my Rat Rod challenger, even tho I'm sure the 2" would be better.John RR said he got some good #s from the 1 7/8".Rvoyles, where can I get that 170.00 price on the 1&7/8" comps?
Thanks for all the good info, guys!Saves me time and $!
Casey

Still hoping for the final Zippy stamp of approval.

Casey,

Yep he is right, the pn really is 5209 for the 2".
Brain fart
They have one slip tube that wraps around the torsion bar, and they do have a 3.5" collector ring for a bolt-on exhaust.

The 1&7/8 also work fine, but most of them need 2 small dings so the plug socket will go on. A few folks have had good luck not dinging and instead using an open end wrench for spark plugs, or grinding the socket to shorten it, but I never tried that.

Besides budget, the only question that is left is which one to use? IMO the 1&7/8 are fine for a street car. Mine ran low 11's with 1&7/8 through the exhaust, and picked up nothing with open headers. If it weren't for the never ending quest for a 10 second run, I wouldn't bother with the 2".

THANKS ZIPPY!!!!!!!!!!!!!!!!!!
Aloha, Casey
