Cousin is taking on a love job...vt 304/4l60e donor car.

Trying to scrounge up as many factory parts to do conversion cheaply then afterwards if owner likes it he can spend money to make more & road legal.

They have lh/x engine brackets

I'm giving them hq sump + pickup also commodore ling nose crank + w/pump pulley.

Was thinking they could modify trimatic trans member & use stock 6cyl yrimatic tailshaft?

Weld in ring to fit vt fuel pump?

Just planning stage & scrounging for parts.

You can use the pulleys on the EFI engine.

Use cast iron exhaust manifolds but use V6 pipe plates as the V8 ones are bigger and foul the sump. Not sure if they fit Torana though, work in a Holden but one of the original Torana ones differs to Holden so might have issues on same side.

TH350 crossmember, best to get one off EBay with Engineering papers.

Will need a V8 banjo and tailshaft will bee too long.

Cousin's job is get it in there & get it running...he wants all parts ready to go try to do job in a week or two & owner takes car back home to finish off all the small time consuming parts.

Headers I told them to get steel vn to vs calais or hsv as that is what I used on lc gtr where the bottom was modified to suit.

Used stock trimatic tailshaft on bitsa vk although tad long to street drive but ok to start & move car ironically stock tailshaft was perfect in 304efi lc gtr but it was getrag.

Wonder if lc/j tailshaft work better.

Told owner if like end result put b/w diff in although want to keep it on 13's with hubcap or similar look.

Not a fan of serpentine setup I do have pulleys to make it v belt with long nose pump but prefer short nose pump single row kingy pulleys.

I want to have parts together so it's ready to do end of year.

Might have a scrounge around shed this weekend.

All of the stainless exhaust manifolds I’ve had were cracked. That is why I always use the cast iron ones.

Standard Torana shaft will not fit, too long. In the past I have dummied up a stock TH400 tailshaft with a 1-tonner front yoke for a 4L60/4L60E behind a 308/5.0 in a Holden and it’d work. The TH400 shaft is much shorter than 3/4spd/Trimatic, but 4L60 is even shorter. The TH400 yoke is much bigger though. See here
