Hi all I have decided its time for a power upgrade for the ute as everything else has now been done and the standard 308 just isnt cutting it anymore.
The options which I have narrowed it down to are.
1.Staying with the 5.0 but goin fuel injected say a late vt engine and running a large single turbo and chasing about 400 rwhp.
2.Second option is goin with a small block chev and running the usual mods to get the desired hp.
Any feed back on this would be very helpful.
The ute will only be a weekend car from now on and maybe the ocasional run down the strip so fuel economy is of no concern anymore.
cheers

I sort of agree, but a 380-400 cube Holden or Chev small block may be a lot easier depending upon what is there now.

What about the Big Paw? Be a little unique? http://www.torque-power.com.au/big_paw11.htmHolden based motor that can be taken to 500 cubes and bolt in place of any 253/308 Holden. So you get the grunt you want, and its a dead easy swap. Of course youl |

yep,we could to the above, get the C.O.M.E. big cube kit, and after you do all that, and spend all that money, you can get a ZZ502 or even a 502HO, brand new, that makes heaps more ft/lbs without even raising a sweat and on pump gas without a drama, for t

With an M21 or Supra and 10 bolt youll have to stay 308. Youll have to run a TH400 or 4spd TH400 and 9" if you want a 500hp engine.

I dont know much about Tremecs. A Muncie M22 will handle decent power, so will a properly built Toploader. These are what Id use if going manual, although a 4L80 would be my choice.

the muncie is a good box, but getting a bit scarce now.
some of these newer 5 sp boxes have the shifter way back, like near where your seatbelts come out when they are put into holdens.

HZ sandman Van 6/10 or better. |
Old holdens brought on the spot, quick decision, cash paid. |

Possibly. A stroked 308 might be a cheaper option for you so you can re-use radiator, exhaust, engine accessories, mounts etc.

SBC is a solid bet, but before you do, read Street Machine August and September 07. Bob Kotmels tech articles are entirely devoted to Red 308s. Different builds, specs, outputs etc. Great stuff. |
