Stainless Steel Manifolds

Egad, no cla$$.

Easy fellas. There are a few members here (including myself) that have spoken with Allen personally. He is a good guy and appears to have a quality product. We are currently working with him to try and establish a good relationship here. A few of us anticipate purchasing some of his manifolds within the coming months and will share our experiences with everyone. These could be a great option for many of us, as there are currently very few manufacturers of aftermarket marine exhaust manifolds for small block Fords.

Stay tuned!

Tim and Doc, don't forget to keep my order in the queue for "sold" SBF sets. Thx.

Doc, Does the $1,350 include the Riser as well? What is SBF and SBC? My 'Fish' has the 351 engine so is the a SS replacement for that available as well. Jerry

Attention; Hi Tek S/S manifolds for sale.....
Just got off the phone with Allen at Hi Tek,The Boat Doctor is now the Southern Dist. for Hi Tek S/S Manifolds.
I gotta buy 5 sets,SBF or SBC, but under these guidelines price per set will be 1387.00 USD this includes shipping.
I think we have 2 committed already,we need 2 more to firm up the order.Call me 318-386-2825 Billy Sutton.........boat dr   

Do you know what kind of performance gains there would be on a EFI GT-40 ?

ok please check on price and get let me know. do you know when we would be getting them?

boat doc when is a good time to call you? As I still have a hard time keeping track of who lives where, what time zone are you in?

And Tim, no problem with these and the P heads as there is with automotive headers? I was hoping that since they curve up that it wouldn't be an issue compared to auto headers going out and down. Just checking.

Reid, a picture's worth a thousand words:



Since automotive headers swing down and marine headers swing up, we have no fitment problems. Plug angle is actually much improved over the stock heads.

Boat Dr, Ill give you a call today.

Yes, those sounds like BBC w/ 4" riser numbers.

79, you don't need to go back to school,it's my math that is suspect. Total weight of 2 manifolds is 62lbs.2 Risers weigh 42 lbs. this adds up to 104 lbs. subract 12 lbs per manifold and you only lose 80 lbs.
My digital scales, i hope,will show the weight of the Hi Teks as Allen advertised them.Sorry for the wrong info.........boat dr

boat dr...how much are the polished ones??

$1687.00 was said earlier.

I have been very happy with the Hi-Tek headers so far. As mentioned in a previous thread they bolted up almost as easy as the OEM ones with the exception that the way the headers come out and turn up I was only able to get a socket on about half of the bolts but again I don't have a vast selection of specialty sockets etc. The remaining bolts had to be tightened with an end wrench and with about 10 hours of use none have losened up so far. Absolutely no clearance issues at all anywhere on my 92 SNCB. Did not have to adjust the carb settings with the exception raising the idle about 100 RPM. Took it to the lake and picked up 4.0 MPH. I have also added the new style DUI HEI style distibutor and a Weiand intake as well. Also changed to a rear billet metering block and upped the jet sizes and the boat is now running about 52.5 MPH with 14 degrees of timing which I have been very happy considering these are only bolt on mods. I mentioned to Boat Dr. that the last few times out I am still having the starboard side run hotter than the port side by about 70 degrees (140 port to 210 starboard) only at idle but seems to normlize under way. Hope this helps.

Thanks!
