Chev 307 - Aussie V8 | Holden - Ford

307 · 04-08-2008, 07:01 PM

[font=Arial]Hey fellas im fairly new here i was just wondering if youse can tell me what holden would fit a chev 307 the easiest as i have a old motor and also what transmission will bolt up

Hay 307 and welcome.

Best Holden for a 307 SBC would be a HQ Holden, as no modification is really required. You will need to source engine mounts and adaptors. Brakes should be OK.

Best tranz would be a T350 in my opinion as no real mods to the floor pan are required. A new cross member that are readily available will be needed.
Tail shaft would need to be custom made.Holden did make them but good luck finding one.
Stock banjo diff can handle a 307 if you don’t give it a hard time. If fitted with a 10 bolt even better.

You would have to check with your local transport authority to see if a mod plate is required.

Thanks mate .. ill keep an eye for a Hq and start working on it and put some pics up in no time

hey 307 & coop. aren't standard trimatic tailshafts right for a t350? I may be wrong, but the yolk is the same isn't it? dunno about lengths and it would depend on the diff being used I guess.
but yes 307, an HQ would be the way to go, a simple build with few hassles in the long run.

COOPHT · 04-08-2008, 09:00 PM

I think a T350 shaft is different but the yoke I am not sure about, ASH. But hay nothing would surprise me.

Tri and Aussie are the same.

Jake07 · 04-08-2008, 09:18 PM

Turbo 350 / 700 and trimatic run the same yoke just tailshaft length varies.Turbo 700 be real nice behind 307 great with the overdrive.

mrprem · 04-08-2008, 10:39 PM

Trimatic, Aussie 3 and 4 speed, t350, powerglide, Muncie all can use the same yoke.

hq74 · 04-08-2008, 11:22 PM

transmission cross member does not have to be changed. when i did my v8 and turbo 400 conversion i used the old trimatic cross member. all i had to do was drill two new holes for the transmission mount

i also heard that they would fit in a hg kingswood can you fellas please give me some info if you know thanks

wabbit · 05-08-2008, 07:16 PM

they will indeed.

factory parts will do the install for this, as well

Ugly Ash · 05-08-2008, 07:19 PM

harder to find the bits for, such as sumps and stuff, when you co find them they are more expensive.

307 · 05-08-2008, 07:19 PM

How much will the conversion cost mate

307 · 05-08-2008, 07:20 PM

Supposably the chev 307 i have come out of a holden brougham how would i know which sump is what

It depends on what you have 307 you need to modify the crossmembers on the tkg holdens to suit t350 and 400.If all you have is the motor you will need engine mounts sump and extracors.

gas 84k · 05-08-2008, 07:25 PM

The sump you have will suit tgk's
