I ordered a set of 6208's for our Mav 351w. I have not installed the engine or used the headers and i am thinking of sending them back if i can find something with 2" primary tubes. I am not looking for something that will bolt on without any modifications I am just looking something that will fit around the engine mounts and run as close to the block as possible. Our car has a MustangII or Pinto front end that needs to be reworked, and we may be able to modify the frame to fit the headers when we go back if we have something to work with. The heads have the double bolt holes so an adaptor plate can be bolted up to them if that is necessary too. Any help would be appreciated.
hooker headers are the best fitting headers that i know of for our cars. not sure the size of the primaries. i just know they fit... i have them on my car
what the hell you got goin on that needs 2inch primies? i believe Riporter has 2 inch primies on his top elimnator Comet thats pushin, i believe 800 hp 1 3/4 should be more than enough
anything over 400 is a serious engine... anything more than 600 and you better have diapers on when you go to the track but for a 2" primary... anything more than 650 hp i would guess
I will put it this way: Any 400 cube or smaller engine that truely needs 2" primary headers (NA), will NOT be streetable. I know some Cleveland and Boss 302 headers are 2" or better... but we all know that those engines are not gaining anything streetworthy with those headers, nor do they truely need them. Dave Edit: In terms of street cars, and probably most folks on this board (that do not have drag cars), any engine with more than 1 hp per cube, is pretty serious. Assuming NA...
Wonderful, I have an idea on what a "serious engine" is now. I think mine will fall in this category, so........ any suggestions/info/help on headers with 2" primaries that may fall in the range of what i am describing? Also they need to terminate under the car as a muffler system will also be used.
I will add to my post... If you use mufflers on an SBF, you don't NEED 2" primary headers. Seriously though, if you do want a set, you will end up fabbing them up. I don't know of any maker that has SBF headers with 2" primaries. That being said, there are lots of serious SBFs out there, if they needed 2" pipes, someone would be making them. Agreed? Maybe you could get a set of 429 CJ headers and cut off the flanges, do a little re-arranging and make a set from those. Just a thought. I wondered if you could use some Cleveland headers, but I don't think there is a way around the angle of the exhaust ports. Windsors pipes come out the side of the engine perpendicular to the ground, while Cleveland/Boss ports come very close to pointing straight down at the ground. That is how those engines fit such large primary pipes into small cars. I had a set of 2" pipes for a Maverick with a Boss 302... Again, the exhaust port exit angle put these pipes below the subframe before they started. There was no issue of having to come from the side and round the block. They were also already below the steering box and such too. All the pipes just went straight down from the ports, hugged the block, and then turned 90* to go straight back. Would have been much easier with an engine plate mounting system... just do away with stock engine mounts. Also had to do away with the oil filter on the side of the block. The filter had to be relocated and the hoses can't come out the block straight. They had to have a flat plate with 90* hose exits. Hope I am giving you ideas to help if you decide to fab some up. I apologize that I don't know of any 2" headers for an SBF. Dave
Dave, that was great. Thank you so much for that idea. That is all i wanted from my post. Some ideas. Any of you guys ever heard a hard head makes a soft A$$? Well I am hard headed i guess, I just have my mind set and want to see what happens. If nothing else you can learn from my mistakes, or maybe a success if i am lucky. Think of it as me testing this idea for THE FORUM!! Dave, mounts are out and motor plate is in. Thanks again.
