Hey its so easy to do I did it in my 71 Australian Charger - its essentially the same engine bay as a Demon or Duster other than the RHD.
I even used TTI B/E body 2 1/4" headers. Fabbed engine mounts and mounted them to the top of the frame rails and used an engine plate, then fabbed a...
I'm using OE TQ jets /rods on the Pri side as I have a good stash of those, Sec side I'm using the Holley jets.
No need to mod the Pri side for Holley jets due to jets /rods I have already have available.
Rusty - the measurements as to shortening the TQ jet and air bleed/emulsion tube are in the OP. I'm not sure what seals you're referring to for Sec jets, the TQ O rings are on the Pri side no ?
Bewy atm I have # 85 Holley jets or about a .100" orifice, stock 318s ran around .110".
Hey Bewy driven it yes.
The engine is a 283 SBC, hyd FT cam with ported power packs in an OT light hot rod with a 5 speed and 3.9 rear. Will likely be around 285HP max. No reason you could'nt use it on a 273 or 318 either.
The car drives great, has great throttle response and great on the fuel...
Well the jet mods have been done.
Very easy and AFRs in the mid 12s at WOT. Note the Holley jet #s to actual orifice sizing t to enable comparison to TQ sec jet orifices.
Finding a 1/4-32 tap was a snap.
The Sec spray bars were modded as well.
Thanks John, yes I know Holley jets are different at 1/4-32.
Do you know what the threads per inch spec is on the TQ jet ? Would they be 1/4-28 ?
Thanks !
Bewy I saw that post mate (good stuff) and have done that mod on another 800 TQ. Great number in the obese Injun too haha.
I think this SEC / Holley jet mod is done by the Super Stock guys. The mod the rear jet and emulsion tube / Hi speed air bleed to suit and also retap the PRI jet thread to...
Sure...I cant remember which forum I saved the text from some time ago. I do remember it was a known carb modifier/tuner - could have possibly been a Super Stock racing forum.
