302ci Ford small block

[Ecosseven]

A few questions.

1. What are the power and torque figures for a standard 302ci Ford V8 on a single 4 barrel holley carb?
2. Any ideas how much a fully reconditioned engine with all ancillaries will cost?
3. Who would you recommend inn the UK to supply the engine and ancillaries?

Thanks.

Martin.

If my memory serves me right, the original 4 barrels had around 250hp (Boss 302's had around 290hp), 2 barrels had between 210-230hp. However many crate/upgraded motors nowadays are getting in excess of 300hp.

But I don't think it will fit in your Caterham?

Cheers Mike,

Not thinking of dropping a V8 into the seven!

I was thinking about building a kit car though, probably a cobra replica or similar lightweight sportscar.

All the best.

This is mine to give you a benchmark.

The engine is 40" up on bore and 20" on crank Most people warm over the engines and you can go very wild but this engine is probably about where you want to be IE well re-conditioned with some bolt on goodies:

Spec is:

302 Block
1968 289 hi po heads (std 302 heads are smogged and poor for performance)
screw in rocker posts
Comp Cams roller rockers
Crane 270H Cam
Wiend dual plane intake
Holley 650 Double Pumper
MSD Ignition

This is all mated to a Super T10

Power from this is approx 285 - 290 Hp (flywheel)

Ecosseven, joking about the seven, lol.
I was a member of the cobra replica club. Never got round to buying or building unfortunately due to my father passing away at the time. However there was a guy called Peter Jones who was the editor of their mag Snake-Torque. He used to build Ford V8's for the members around 350-400bhp (351cu), can't remeber the price, but it was much cheaper than anyone else, he also was a very friendly chap who would help you with anything to do with the build. Although this was some 10 years ago.

Their website is www.ac427.com

PS I did a lot of research and would recommend a Gardner Douglas Cobra or an AK Sportscars Cobra or a Dax Cobra.

On thing to watch with the Ford 302ci/5 litre, is it has been around for a long time in various guises.

The early HP readings for it are either optimistic at best or plain outright lies at worst.

Anything pre 1973 is rated in SAE GROSS which means without any exhaust, ancillaries and often a blue printed engine and fiddling with external conditions (temp, humid, etc.).

In the late 70's power was done to 134bhp (maybe even lower is memory serves ~120hp). In the 90's Ford got the power back up to 225bhp, but they had to change their rating system and all engines lost 10hp because of it.

So sadly it's not a powerhouse by modern standards. And chances are the older engines were less powerful than the latter ones.

300bhp from 5.0 litres is a fairly stout motor but quite possible with the right setup.

From what I've read it doesn't massively out perform the Rover V8 for the same displacement, it's just you've got more displacement to play with. And strangely enough a lot of vehicles which used this engine actually were not that heavy, hence they could be made very fast.

Martin,

I was looking for someone to do work on my 302ci that is sitting in my Mk1 Zephyr. On the Mustang OWners Club site, there is a guy called Phil that is very knowledgable and experienced with these engines and does a great job.

here is a link to a mate's car that went in for a 302 to 347 stroker conversion...

I have it on pretty good authority that a 347 isn't a good long term option due to piston / stroke and ring landing issues. a better bet for power and longevity is a 331 stroke.

Surprisingly good power is available from a SBF. Could even go with a 351 windsor for a stronger block and better head sealing especially if your going for power adders. Good aftermarket heads make a big difference when combined a balanced/matched cam/intake package.

351 CLEVELAND...that's the boyo!
