Hi Guys back with another question, I am starting the newest project and was wanting to put a V8 into an early (EK) Holden, but I am not sure what way to go? I have narrowed the choices down to either the 307 chev or the 308 Holden motor, from round the early to mid seventies (pre pollution) this keep in with the "Old School" theme of the sedan, and was wondering if there were any significant differences between the two to make one a better conversion than the other, I know there are the chev fans and the Holden fans, but what fits best, availability of dress up and go fast period parts etc will all be stuff that I will need to know as well Matt P.S. any advice would be great!

Got a better idea - a 283! These were actually available, and in Australia from 1957 through to around 1967. If you get a post 1963 block you can stick a SJ 327 crank in and make it a 307. The 283 is a sweet little engine, and I think the Chevy will fit e |

Thanks Byron, I am thinking of the T350 or 400 auto, and that sounds like an interesting plan! I want to keep it looking like it could have possibly been a factory installation, if they ever made one! I know there are a few chev conversions out there, wil Edited by user Friday, 30 June 2006 8:03:33 AM(UTC)

All small blocks from 1955 to the very last of the them (technically they are not finished yet as you can still buy crate motors) are identical dimensionally. That means 265 right through to 400 cubes.
As for picking them apart you do this by the casting |

Hi Guys.
While I like SBC engines, these days it's gets a bit expensive to build a motor & do the conversion etc.
For an EK, the SBC is quite heavy, why not look at a Commodore V6 conversion, there are guys around like Pat Gardiner with all the bits |

You could use the Commodore V6 as Dr Terry says or you could use an old school carby buick V6 such as this one: http://cgi.ebay.com.au/w...e=STRK%3AMEWA%3AIT&rd=1

I actually agree with Terry, but I was answering the question about an old school V8 conversion. |

I'm interested to know how the Hemi stack's up to some of the choices??
With any "shoe horn" into an early model the issue of motor and exhaust clearance come to mind first.
I know my V6 in EH is tighter than I would like but some of the V8 types I've s

Yeah, I thought about the late V6 conversion, but would like to do an eight, then I thought about the late commodeore 304, but it comes back to similar pain in the b*m stuff for EFI and anti pollution stuff, that is what started me thinking about the "Old |

I'm doing an EFI 304 into HZ right now, but that is way easier than an EK. Everything is easy though. The biggest problem you'll face is clearances. Pollution equipment is absolutely a snack though. All you need is a carbon canister, catyltic converter an Edited by user Saturday, 1 July 2006 4:47:10 AM(UTC)

Thanks again Byron, what about all of the return lines and swirl pot stuff I have heard about for the EFI? is it a PITA?
Secondly if I was to use an early block, any suggestions? and would the late model EFI stuff bolt on?
Maybe a complete wreck from a |

Is it true that the EFI V8's are cheaper, with exception to the cost of the engine/running gear itself, to install than the V6 because an early red/blue V8 sump will bolt straight up, rather than requiring a custom sump(in the case of the 6)?

Yes. Everything else is the same too:
Radiator, hoses, bellhousing, engine mounts etc etc. It's all interchangeable off HT-VL (albeit the differences betweeen HT-VL stuff in between). All you have to do is use the HQ-WB sump and engine mount adapters a |

With adding 304 EFI on top of a red block - won't you need a crank sensor - how do these bolt on? Also, Does the difference in capacity cause dramas?

Hi Beige Hornet.
The crank sensor in a 5 litre EFI Holden V8 is inside the dissy, instead of points or a reluctor. When they say use the top end of the EFI set-up, this includes heads, manifolds, cam & the dissy.

Thanks Dr Terry,
That's been an age-old question I've been wanting to ask!
