Which is Better 307 or 327 - Aussie V8 | Holden - Ford

EarlyHoldenFan · 14-11-2007, 09:06 PM

Hi guys I am in the process of re-powering a couple of old Holden projects I have on the go at the moment (FB - EK Holdens) and I was wondering peoples opinions on what is suggested I have narrowed it down to the 307 or the 327, the main uses will be street driver and will be rebuilt to fairly standard specs. I will also be towing a couple of vintage caravans with the cars so Torque will have to come into the equasion as well.

Cheers and thanks in advance

In Queensland, due to the weight of the cars, am limited to 329 cubes or I would have gone with a 350, but seeing as that is out of the question these two are my best options.

there's no substitute for cubic inches

what they said..... no substitue for cubic inches. cant have the 350 then go the 327 just give it a right old kick in the guts with nice cam for towing and youll be good. if youve got the extra dollars then nothing wrong with working it a bit

i agree....327 are the go. mine's been running for over 10yrs now never missed a beat.

I say, go the 350, the block is the same as a 327, what are they gonna do, pull your motor down to check the crank?

No but it's easy to look at engine number behind dissy to see what engine it is. If they take it over the pits they'll find it.
Go the 327, nice cam, bit of head work and you'll get an easy 350 to 400hp that will tow that caravan of yours anywhere.
Go the EK's

HK 327 had small journal, and the last HK of them, big journal 327.
any one, have a opinion on this.

Pff go the 327 block and fill it with whatever size crank you want!

I agree... but if your going for that extra torque stroker is the best option.. 383 as van said would they pull down a engine to check if its a 327 all depends on what you want to do?? but pro068 has a good point that a 327 with a tow cam will tow a caravan and would bring the cost down alot..

Thanks guys, considering I am not trying to fry tires and I do want to at least stay on the right side of the law till it is registered, I will go with the 327, treat it to a cam and some nice head work and if that cant tow the van then nothing will!
Thanks for the help and ideas

lol at wabbs for bringing up previous comments refering to people with less intelligence than a pet gerbil!

Cubes wins every time, good to see u decided on the 327.

If your using it for towing i would look at a set of vortech heads they make great torque and with the dollar at the moment they would be a great option.Good runner size on a 327 .
