T5 behind 350 stroker. 4 bolt mains. X. Larry perkins red block. Into hj van

[L31]

G'day guys! Just bought a new stroker to build up. Red block. X- larry perkins 4 bolt mains, harrop stroker. Original bore.
My mates keep trying to push me to use a supra 5 speed. I know they're a good strong box, but have my reservations about mixing it up to much. Will a t5 bolt up ok to the red bloke? Or am i up for : Drilling holes or adapter plates etc.... And does anyone know where the shifter may pop up in the cab? Cheers. L31

When you say red block, do you mean HT-HZ/VB block converted to 4 bolt? Or do you mean the VK GroupA A9L red painted engine with VC prefix engine number? Or on the outside a VN HSV SV5000 engine with red rocker covers (VE prefix engine number)?

If it is the former it may be a TH pattern (auto) block and then a VN-VS T5 bellhousing will bolt straight up. If it is the VK GroupA block it'll be a 4spd block, and you'll need a Dellow or CRS bellhousing unless you can track down a VL Walkinshaw bellhousing. If it is the VN engine it'll be TH pattern.

I wouldn't trust a Supra or T5 to last behind a 350ci stroked 304/308 block if you are going to give it a hard time. Either will be OK if you only want to cruise in it. If you want to pound it, use a Muncie or an auto.

For the shifter on a T5 talk to the guys at gmh-torana.com.au, they are all over which box to use to get the shifter in the factory aussie 4spd/T-bar hole location. I think they use a Falcon box, which is a diffferent bellhousing pattern again.

Vk group a vc prefix. Will a blue meanie bell housing bolt up to the vk group a block? And does a t5 bolt into the blue meanie?

Blue Meanie is a VK Group A, or one of them anyway.
Only a rare optioned T5 HDT Group A or a VL Walkinshaw box and bellhousing. Otherwise you'll need an aftermarket bellhousing. Talk to Mal Wood Automotive or ask the guys at gmh-torana.

A falcon extension housing saved me cutting approx 20mm out of the floor remember I've got a crap v6 not 308 so im not sure if there's a difference the falcon extension bolted straight onto my v6 box needed the housing and the top cover off falcon box

You will destroy 3rd gear on a T5 with a stroker. I'd use a Tremec 5 speed. They are a very robust gearbox. A couple of mates ran T5's in rally cars and they where having continual 3rd gear failures. After saving there pennies they both fitted Tremec's and have had no failures to date. The Tremec is based on a Ford Top Loader but is 5 speed and a fair bit more refined. Google Mal Wood Automotive as there are the Australian agent.

Cheers. What about the 6 speed. I know you can bolt them up with a simple adaptor plate?? DO YOU HAVE AN OPINION ON THE SUPRA? CHEERS L31
