318 poly
 

Anyone try this combo with 2 BBL in a 60's car? Still has original factory HP. Way more than the LA 318.

Re: 318 poly
 

It would be a nightmare.....What is it 230HP or so?

I race a 63 Belv. 318 poly with 2 fours in AHRA Formula Stock back in the day that I traded straight across for a set of Max Wedge Heads to Burbank Speed in the early 70s. It ran in the mid 12s.

A 2 Brl. 318 would not stand a chance against our 318 Thermoquad
O/SA Wagon which is at 230 HP!

230 with a thermoquad ?!?! :eek: :( :eek:

Re: 318 poly
 

If you take 45 hp off like the LA engines, it would be reasonable to consider.

Re: 318 poly
 

2V polys are at 195.

Re: 318 poly
 

Finding a cam for one would be a nightmare, but they are solids and adj rockers. Read of a builup on one of these engines, a little head work, cam and good intake, made over 500 hp. Briggs and Stratton valves in them.

Re: 318 poly
 

The 62 4 barrel would be great if it were rated around 220. Other than the lifter layout for the canted valves, the shortblock is no different than an LA 318 or 340, it uses the same AFB as the 361/305 with 1.84/1.56 valves and these engines can be had for free although the mani is usually few hundred. Find a clean 62 Dodge or Plymouth 2 or 4 dr and have fun.

I was thinking of the 2 bbl combo in a A body. Well tuned that combo produces a strong torque curve. With a B&B motor and a stocker cam???? How easy to convince NHRA for a 318 LA rating?

Re: 318 poly
 

They were never made as far as I know, the A's got the 273.

Re: 318 poly
 

No A body poly 318 every produced.

Re: 318 poly
 

1962 318 4 bl at 260 the way I read class guide.

Re: 318 poly
 

A 62 dart is a B Body

Re: 318 poly
 

I know that (I raced a 62 Dart Wagon in G/SA).........I was trying to highlight was that the 260 HP of poly way too high compared to 318 Thermoquad
at 230 HP with way superior CFM carb!!!

See my post #10

This is the new era of NHRA that doesn't matter just send a letter and have it added anyway.

Re: 318 poly
 

A bodies never got the 318 poly, just the B bodies and trucks.

As far as I know, Schneider Cams will grind you any spec. poly cam you want. They will regrind your cam and I think they still have cam blanks.

The bottom end of the poly motor is the same as the LA motor. Crank, rods, etc. are all the same.
