Re: what combo is better ?
 

I agree with the 327. I like the fact that you can use a Holley carb. and you will need the extra cubes to lug all of the weight.

Re: what combo is better ?
 

I could be wrong,,but I'm thinking the only Holley carbed 327 in 66' was the L-79 combo, which was available in Corvettes, Chevelles, and Chevy IIs. I don't recall it being in a full size Chevy, let alone a station wagon. I'm sure somone on here will set me straight.
That L-72 427 combo would be wild, if its legal. I can see class eliminations for D/S when Ben Wenzel looks over in his 67 Z and sees a wagon in the burnout box with him!
Might be one big parts breaking machine, but could be fun. My 2 cents.

You won't like the fact that it was a 540 cfm Holley with the same rating as a 750 Q-jet.
The 66 Chevy II did not come with the Q-jet originally. Only the Holley or AVS .
The 67's came Qjet equipped ,so NHRA relented for the 66's too.

I f you want more cubes ,how about a 396/325?

Now that would be a really good combo but a load to tow!

Re: what combo is better ?
 

I had a 66 belair s/w for a few years . Ran IHRA and was fast with the exception of Lee Tuttle. Car was 1.50 under . We were at Rockingham Nats In October 04. Lee was 1.51 under (not trying to protect combo) and i was 1.31 under(trying to protect my combo)Needless to say we got HP on Monday. Sad thing is Lee ran IHRA twice a year. Had 198 low gear and 6.14 gear and loooooose converter,with 30x9 hoosier radial.Boy do i miss that car now. I think it weighed 4260 lbs. and ran a 13.84 .

427/425 D/S x2!!!

Re: what combo is better ?
 

It's definitely a tank! What kind of RPM's would you pull through the traps? I was thinking of starting with a 4.88, but if you've had luck with the lower gears I may have to reconsider.

Thanks for the help!

Thanks for the info guys. I have the car. It has been a 283 r and t car most of its life.I have had it up for sale. No one has stepped up to the plate to purchase it. So maybe after I get my current car running under, I have toyed with the idea of spending the next 5 or 6 years building it with my son, so he could race stock when he gets old enough.

By the way 6:13 gears 2.18 low gear set in the trans are what help to make the 283 combo work.

Re: what combo is better ?
 

I run a 5.57 in my 4400 lb. wagon with the 350 ci. A 5.86 will make that 283 GO

Re: what combo is better ?
 

Hi-For that car these guys are right-ya need lotsa gear and buzz it!!!!
