The V8 Owners Forum -

I trying to find myself a Holley as I can't afford a webber. I know I probably need only the 390 or 450 on my current 3.5 ( later 3.9 ) but there seems to be a myraid of different numbers associated with them. I don't need auto choke or anything like that and was wondering whether anyone had any specific recommendations of Holley.
Thanks

Just ask / look for a 390 Holley. Check it has the metering plate with replaceable jets fitted, as stock they don't (or didn't used to) come with them.

Thanks for that.

No worries. Should've said, the 2 model nos are 4150 and 4160, these come in different cfm's. 4160 has a non-adjustable secondary plate, 4150 has a proper metering block, but 4160 can be converted to 4150 anyway. I think all 390s are vacuum secondary but someone else will correct that if wrong. Basically, all the shops and second-hand ads just call 'em 390s.

There is actually a mechanical secondary double pumper version of 390 cfm carb, but you are very unlikely to come across a used one.

See http://www.holley.com/HiOctn/ProdLine/P ... 507-1.html

Holley #8007 390 cfm are all 4160 type carbs with metering plate on secondary side.

Sean,

White Performance (ebay shop whiteperformance1) are selling brand new Holley 4160's for $213US. Factor in delivery, import tax and Vat and you might get one for around £200ish. It'll need re-jetting but then what doesn't??

Cheers,

Ian

Thanks for all your advice chaps.
