3/8 line matches 6AN. Slip the tube nut couplers over and then flared the steel line. Connected pretty easy.

I've almost got the Performer off now. Just need to drop the coolant and finish the bolts. Hopefully when I get back from work I'll have it back and buttoned up in a few hours.

How’s it working with the Torker Rowdy?

Well, ****! Despite decent planning, I've gotten myself into a spot where I'm getting indecisive. Supposedly, my 357W has a flat tappet XE284H with hydraulic lifters in a '70 block (oddball I know). I think that cam is just too big for a street driven car. I don't want to pull the engine, because if I did I'd probably be better off rebuilding it to a 408. I want to try the Sniper with what I have, as is. I also swapped my heads for a set of AFR185s, and bought some Doug's longtubes (that don't fit even though I called to confirm they would). My mechanic recommends sending the headers back because I already have mid length headers. I was hoping to drop temps (jet-hot) more than pick up HP, but he thought I'd be fine with what I have and said the jet hot shouldn't make as big a difference as everything I've read online.

So, I'm looking for opinions, mostly on the cam. Do I go forward with it (it was in the car before) and hope the Sniper can manage, or bite the bullet and order a better match for my combo?

As far as the cam goes I think you will probably be ok with that cam, I have a xe274HR in my 347 and wish it was bigger. As far as the long-tubes I have no comment about fitment but jet-hot coating (or really any thermal coating) makes a big difference. I had my hooker comp headers jet-hot coated a number of years ago, and there was dramatic difference in under hood temps, plus because they didn't get as hot, your were able to work on in and around the headers sooner with out the risk of burns. (and it just looks nicer)

Maybe I'll just send what I have out for a ceramic coating. I e-mailed FPS and they want $1200 for a similar set.

Did you check with JBA headers? I bought mine ceramic coated for around $500

The Doug's I bought were jet-hot coated off of Summit and with the sale were right at $500. It wasn't the price. They didn't fit. I even called Doug's to ensure I had the right part number for my combo ('68 w/ z bar and TC steering rack) because the Doug's website is terrible. I should have trusted my gut.


I don't think longtubes will really offer that much more HP gain. I was primarily looking for the temp reduction. I'll put it off until I do a full stroker, down the road.

What I'm saying is that the JBA's seem to be about $500 or so cheaper than getting the others you mentioned ceramic coated by FPS, maybe FPA? I'd ship the Doug's headers back and get JBA's. They make a shorty/mid-length header that I have personally have on my car and love them. They're a great fit and a great product, I'd highly recommend them.

Does anyone know if it would it be possible to get the Hyperspark Ignition, Coil and Distributor and install/run it with a carburetor for a while and then add the Sniper EFI later? Or do the HyperSpark parts only work with the Sniper?

I’m going to answer my own question. I called Holley Tech. No, you can’t use the hyperspark package with a carburetor.

For those interested.. I finished installing the Torker II today...

Other than a coolant leak (my own fault) I am VERY pleased.

Sadly it got dark as I took it for a quick test drive, but my initial impression is a good one. Idle is more stable. It fired on the first turn of the starter. It pulls away from a stop easier and generally responded smoother. I only did about a 2km loop.. but I'm happier. I'm sure as the sniper adjusts it'll only get better.

Thanks for the update. Was the difference between the torker and the performer significantly noticeable? Would you say it would be worth switching to a torker if you have a performer?

the TBI style fuel injection setups just like single planes more. A dual plane like the performer will be ok if thats what you've already got, but a single plane will just be better all around.

It depends on how picky you are. I drive this thing. A LOT. So I wanted it to have a nice clean and smooth idle and off idle transition. Mission accomplished. My good buddy switched to a victor JR (he has a cowl hood) and had the same remarks I did. Noticeably better.
