Building 69 Biscayne 427 335h.p. H/SA
 

Building 69 Biscayne 427 335h.p. H/SA. First stocker I have ever built. Anyone have any good advise or tips? Any info about this combo? Let me know. Thanks Scott. Biscayne@aol.com

I believe that is what Steve Hauter (D5 - MN) races. He is accomplished and knowledgeable about what is required to run fast. I think after a LONG time racing that car he has it so it will run +/- .500 under. Based on that and that alone, it's not a project I would tackle. I would suggest more homework is in order.
Good luck!

Motor looks like a pretty soft deal. Just like a 396- 325 except 31 more cubes with only a 10 hp. hit. I don't know how much that big body would hurt, but the motor looks okay.

It's not as soft as you'd think. The weak intake (unless it has a much better intake than most of the oval port Q-Jet 427's I've seen) and the small (.398" lift) hydraulic cam will make it hard to feed those extra cubic inches. Most of the guys I know who have to run that real small hydraulic cam really struggle.

Alan, I can see where that would be a problem, '66 283's are .399 lift. I'd bet it would be tough to make power with.............

I'm gonna give it a shot. Anyone have any idea what kind of h.p. it will make?

Where's that fella from NY (I think) who was a frequent visitor to this site? He built that '68 Impala 396-325 4-speed Stocker a few years back...I think that motor's similar and maybe he can give you some help? I saw him run once when he was trying out the combo....Yours and his are tough ones to make run....I think his name was Will?

There's a lot of difference between feeding a 283 with less than 0.400" lift and feeding a 427 with less than 0.400" lift.

Re: Building 69 Biscayne 427 335h.p. H/SA
 

but not so much difference than feeding a 396...and those do pretty good...still........just would be hard to get anywere in that very heavily populated class...would love to see one though...

Looks like about 510 hp to run a second under. That's less than 1.2 hp per cube. Doesn't look too bad.
Gotta get that nose back down after launch. Lotta wind resistance.

It's been tried before, here's one from the past.

There was a guy up near Cayuga with a blue hardtop (Charlie Tuna or something) that was in F/Stock at the time. It was rated at 370 hp back then, and I remember thinking that was way too high.
So somewhere along the line, that motor got factored way up and then back down again. I wonder why?
Anybody remember him?

Wow, look at those tires! It's a great (if extreme) illustration of "effective radius."
