Maybe a 4bbl SBC Stocker engine with the hp rating beat to death, that a guy would have to spend 30 Grand on to be a second under?

Guess being a second under can be good to qualify but I guess I always wanted to beat someone who had a similar car even if we were both over factored. Always liked class better than ..... I only learned SBC, BBC tear down and work. Got to give credit to you guys who learn the others and apply it to these cars.

Wont there always be a more bogus combo in the weeds? Cadillac, BLown Studebaker, Vega OH cam?

hopefully billy nees, bob shaw, mark yacavone and the rest of the enthusiast ensure the 'BOGUS' combos never end! thanks for your tireless work!

also I prefer to call them "favorable" rather than "bogus"........ Randy Hyman

Without the 'bogus' combos, some of us would never attempt to build a car because it would seem impossible to compete.

Ya know, I really have to ask, how is this combo bogus? It's got an intake port that wants me to try and find someone that can make it smaller and an exhaust port that's not all that good. It's got a big camshaft and big valves but such low compression that you can't really put a "big" cam in it. All but the 74 can only use the small Motorcraft 4350 carb(700 cfm?). It's got a short stroke(relative to the size) and the rotating mass is probably the heaviest of any big block. I can think of a couple of 455 Buicks and Pontiacs that look better on paper. Not to mention that they come in cars that look like the box that my Grand Prix came in and IT'S a box! It must be because they're such a well kept secret that FFFord guys don't even know about them(or choose to not know).

^^ agree

From previous experience with my mid 70's 460s, these are my observations:

The exhaust ports in stock form on those D3 heads are horrible. If you are lucky and find some D3 heads without the A.I.R. injection holes, then grab them. Those bumps in the runner really hurt exhaust flow.

The intake ports in my opinion are way too big. Port velocity is lowered because they are so big.

That 320 factored hp seems a bit high to me. ( considering the valve lift specs and poor exhaust)

Good luck on the LTD build.

Hmmmmmmm, maybe I'll keep my 74 around a little longer.

[kwm]

Would the 74 460 @300 hp same cam, a little bigger valves, more compression be a better combo?

I hope that Vic doesn't mind me answering this, he has a garage full of 429 and 460 stuff and a clean full-sized body popped up for not a lot of money. He also doesn't need to crawl around a roll-bar or wear a fire jacket and pants on a 95* day or fiddle with a harness and a net(Vic has arthritis in his hands). Vic also has a very fast D/E/SA Mustang and a very fast SS/GTG/HA T-Bird that are a real handfull to maintain and now he's(finally) got a car that he can class race AND take to his local track and bracket race without hurting it.
Ya know Dick, when you look at the "common sense" side of this thing, YOU(and a lot of other old poops) should have one!
