Super stock/supergas motor/combo
 

Hey guys,
I found this recommened combo on another website. What type of driveline/fuel system would be common with this combo in a 3800 lbs door car? Would a "stock suspension" work or is this territory for back half cars? I have the bottom end parts to replicate this, but the heads would be tricky. I think a set of cast iron rectangular port would work better since my porting skills aren't a high level. I know the valvesprings aren't cheap as well as the other valvetrain..

Yes you can build this engine to that power level.
What you end up with is a Super Stock Supergas motor with very high compression 14:1+
full max ported big valves 781 heads, forged domed pistons (JE, Ross)
Crane full race roller camshaft 280in-290ex @.050" .750" to .800"++ lift 110-112LSA Full race high rpm valvetrain w triple springs may have over 1000# open spring pressure at full lift.
stud girdle and rev kit.
Tunnel Ram and two 750's/850's or a full race single plane (Dart) and Holley Dominator 1350cfm carb. Big tube 2-1/4 Hooker , Hedman Huster race headers
A GM LS-6 or LS7 forged crank is best.
It requires 114octane race gas or methanol.
regular maintenance items will be bearings, valve springs roller lifters and connecting rods. Needs a custom 6000+ rpm race converter and lots of gear and rpm.
Precision machineing and preparation is required, The block, heads and forged rotating assembly need a full race work up.
These are the basics of a 700+ HP 468 oval port head BBC.
This is not a street motor.

Re: Super stock/supergas motor/combo
 

A Super Stock engine, as applied to this forum, has rules which are mandated by either NHRA or IHRA. Briefly, a SS engine will have to match a year and body claimed and must include factory spec valve sizes, piston dome configuration and carburetor(s). You can have a replacement intake manifold but it must configure to factory (i.e., if it came with a single quadra-jet it must have a single carb intake manifold under a spec quadra-jet. If it came with 2 4bbl carbs it must have 2 4bbl carbs inline or off-set like factory installed). The race organization also specifies the volume of certain parts like intake / exhaust runners and combustion chambers. In a nutshell, that says what you are proposing is a Bracket or maybe Super Gas or Super Street type engine. But definitely not a traditional Super Stock engine.
Good luck and have fun.

Thanks Jeff,
I will try to find a Super Gas or Super Stree section, it's crazy how fast you guys go with Q-Jets:D

If you racall a few years back when they started the leave a class out at the national events Dan Fletcher did rather well with his legal S/S car in supergas. So you could infact do what he is saying just not with the parts he listed.

I have a old Car Craft mag from the '90's and there was a similar year Monte with the same kind of motor. He was doing some sort of class racing but it might have been a specialized catagory..Anyways, I figure a lot of convert&gear with this combo hooking up would be interesting as well..

HEY!!! That's Luskville! haven't raced there since 97.....ok, don't have anything to offer...just don't normally watch u tube and recognise the tracks...


All right, nothing to see here, move along...




(and yes the car leaves nice)

Re: Super stock/supergas motor/combo
 

Yep, it is Luskville! It is close (it's only like 30 miles from my house)..

I found the article it is from Car Craft of January 1997 the classification appears to be SS/FA. The guys name is Bryan Broaddus (he is from Yorba Linda California). The car (1970 Monte) still has to cofirm to a certain things (iron heads, no combustion chamber mods, lower compression, 780 carb, but the cam can be huge 287-288@0.050)
He uses (or used to article is 15 years old ) ladder bars, 6.0 gears, 5500 stall..It runs in the 10.30's...
