Nascar sbc heads of the 70s and 80s?
curious before the era of the aluminum 18* heads of the late 80s came out what did they have to work with back then?
Re: Nascar sbc heads of the 70s and 80s?
I ran a few sets of Nascar take off heads on my drag car years ago. I had a set of "292 Turbo" heads. I suspect these were among the last cast iron heads ran. I had a set of Phase 6 aluminum bowtie heads, and then later a couple sets of "867' Pontiac heads. I'm not sure the exact era these heads came from, but I suspect they're from the timeline you mentioned.
I used to be a people person, but people ruined it.

We had a set of iron Bowtie heads that came from Raymond Beadle's race shop when they auctioned off everything many moons ago. Ran pretty decent on a 12-1 406 with a 264-274 solid flat tappet. 10.70's at 124mph in a 3600lb + '62 Chevy.

292 Turbos until around 82, then 034 cast iron Bowties, phase 1. Not sure what year they went the aluminum Bowtie commonly referred to as the phase 6, probably late 80's.
Next came the 867 Pontiac which was still 23 degree except raised intake runners, teams welded and rolled these to 18 degrees before the actual GM 18 degree heads were introduced.

I have a 1984 ford Motorsport catalog that has the C302-b head and c-302-a4 as nascar head basically a little bit of a Aluminium copy of the 351 cleveland head with raised ports and round exhaust ports.

We were running a "B" prototype in Comp in early '83
Re: Nascar sbc heads of the 70s and 80s?
those ard neat, those woulda came out in 86 according to the article, strange part is only 3 buicks competed in 86 but they seemed to do well with bobby allison winning a couple times and bobby hillin winning, chevy dominated the season but also had the aerocoop to their advantage, what heads did chevy have for 86? was it the phase 6 aluminum?grandsport51 wrote: ↑Thu Nov 01, 2018 5:15 am And then you had the Buick 10 degree heads possibly the best of the era !,

I may be wrong, but I don't think the Dart/Buick head was ever utilized in NASCAR Cup(V-8). If not, it must not have gained approval.tchapps88 wrote: ↑Thu Nov 01, 2018 7:23 pmthose ard neat, those woulda came out in 86 according to the article, strange part is only 3 buicks competed in 86 but they seemed to do well with bobby allison winning a couple times and bobby hillin winning, chevy dominated the season but also had the aerocoop to their advantage, what heads did chevy have for 86? was it the phase 6 aluminum?grandsport51 wrote: ↑Thu Nov 01, 2018 5:15 am And then you had the Buick 10 degree heads possibly the best of the era !,

In the NASCAR Busch series (during the V6 era), the Buick head was 30 HP better than the Chevy head.
Automotive Machining, cylinder head rebuilding, engine building. Can't seem to quit
Re: Nascar sbc heads of the 70s and 80s?
I believe NASCAR killed the V8 Buick quickly. It was too much of an advantage at the time. Like mentioned above,they kicked butt in Busch with the V6. They had a flatter torque curve that raced better.Charliesauto wrote: ↑Thu Nov 01, 2018 10:32 pmI may be wrong, but I don't think the Dart/Buick head was ever utilized in NASCAR Cup(V-8).

Huh - weird thought, I wonder if those found their way into some of the Trans Am cars of that vintage. Would explain why people were running Buick Trans Am cars.grandsport51 wrote: ↑Thu Nov 01, 2018 5:15 am And then you had the Buick 10 degree heads possibly the best of the era !,

Flowed an honest 310 at .600-650ish lift. I had all of these heads flowed at the same place.....only 1
set was the stage2 busch stuff on sheet I posted, the other heads were for stock configuration stuff.
I would imagine that they used they same port since the cylinder size was similar cubes. 45".
