363

I have a 302 based 364 using big bore aluminium Ford Motorsport block.
Matched an Aussie V8 Supercar (sort of like an Australian NASCAR for the foreigners ;p) at a local standing start speed event so performance is adequate.

that is the motor I was thinking of more or less exactly. Who built it up, what do you have in it, what induction, valves and is it hydraulic or slid lifters. Lastly woudl you say its a smooth refined type motor once spining.

It was originally built in the US but quickly developed some issues for various reasons that I won't bore you with but include some of the worst "mechanics" (local) I have come across in my life and one fraudster (also local, and yes police are on his case but they are taking their sweet time...)
Now has new liners, Auscrank race crank, Oliver rods, not sure what pistons ATM but forged, solid roller, ported AFR 185s. 52 mm 8 stack, Motec and dry sump.
Was rebuilt by a friend in Australia.

The V8 supercar and I were well clear of the rest of the field which included Porsche Carrera GT, Murcielago, Gallardo, 458, and various other supercars and race cars.
In other words the engine is strong and revs easily to the current redline of 7500. With current internals I probably should be revving higher but didn't feel the need.

Refined? Hmmm, depends on your definition. Personally I wouldn't say so but it isn't horrible. I can happily drive it from one end of the state to the other, although earplugs are your friend... It runs very sweetly under normal road conditions.
Apart from induction and exhaust noise, there is also valvetrain and ancillary noise. It is fairly smooth under normal conditions considering the cam and really wakes up if you open the taps.
I have a Merc' ML500, that has what I would call a reasonably refined engine. Others would still argue otherwise and say their Bentley is far superior.
Compared to what I originally got from the US and the awful tune it got when it arrived here - yes it is refined.

I think what you have there is pretty much the ultimate in the sbf line up. That big bore and short stroke is by far the best path to 350+ cubes budget permitting.

Tim Thanks for the feedback.

My question about refined is probably misleading. I accept lunpy idle noise etc. My concern is purely with smoothness at revs. My prior experience with long stroke V8 motors(chevy 383) is that they can rev but feel at 6k or so like they really would prefer not to be there and would rather come apart. Even the toyota 4 banger in my elsie is a bit of a long stroker and it has secondary vibes as opposed to being a sweet round rever.

Not expecting something turbine smooth like say a mercedes, but something that revs freely and smoothly as say a stock 5.0 ford does. In other words not a rough gruff motor. the 347 that was at the track recently which also has the 3.4 crank seemed smooth.

If youw ere doing it all again, what woudl you do differently with the motor. Also how much adjusting do you do witht he solid lifetrs?

I am thinking of an aluminun dart block built up by either maybe Keth craft or Benett. Maybe a light crower or other crank, light conrods great pistons, maybe solid roller or hydaulic, light valves shaft rockers with a drysump and carb(love stacks but would rather spend the $$ elsewhere).

Then I see some do and 8.7 deck heioght so you get past rod ratios, but how does one do induction.
Thanks

I would build the engine I had built second first.
I would maybe put the cross-ram on it that it was supposed to have but that's another story and current setup works ok.
Lifters have been pretty good actually. Less adjustment than I thought. TBH though the engine builder looks after it, it's as much his baby as mine I think. :)
At revs the engine is fantastic, revs like crazy and is quite smooth.
It isn't a daily driver so how often they are adjusted is probably meaningless.
The original engine was hydraulic (and had supposedly temporary 44mm throttles) and refused to do anything useful past 6300 RPM

I have no regrets with the current setup so far. Initially I wondered about rod/stroke ratio but it doesn't seem to be an issue. A longer rod would probably be better but then there are other problems, eg: package size etc.

As I came originally from Cleveland's I would be interested in trying some boss style heads but I doubt it'd be worth the change.
