1Gary Back to the original question.Do you guys think this device would lean out the engine at the top end??.

And what does the NASCAR engine have in restrictor plate engines??. Does it involve electronics to the ignition timing too??.

Yes Vinny the 305 engine itself minus the blower will make about 325 BHP. 15+/- PSI is going to fix that up thou.

The low low 7:1cr allows a lot of boost on pump gas. Simple low cost hot rod mods and upgrades allow the 305 to make good use of the supercharger. This 305 will not have a 305 cylinder head on it. But they are a OEM chevy head. Boring stuff.

you cutting the top of the bore to unshroud the valves with heads with bigger valves, or just letting them smash into the cyl wall/deck

1Gary Not a brag.In my racing career I've put on the trailer auto cars of all kinds,stick-shift cars,Blown and N/A cars,the best there is.While I worked at Burlington Air Express I developed a natural sense of time.There I was responsible for turning the plane in 45 minutes or be penalized $15,000 of every 15 minutes over.Yep,one minute cost $15,000 and then one minute over 15 minutes cost a second $15,000 and so on.

I do have that as part of my make-up,a natural sense of time.When I bracket raced before,guys used to grumble about that hitting my dial all the time.

We have a local kid that is using all junkyard parts with a pair of T3's on a crusty 283 in a rusty 80's grand prix that laid down 465 to the tire on 94. Its driven daily....boost is cool.
a 283 isn't a 305, 305's have a big issue that most sbc don't they tend to ping to death,
now my twin turbo 305 was old school carb blow through, before efi or any a/r gauges that the hobby gearhead could afford for tuning, we used a thing called the 1320 .
like I posted I want to see his dyno sheet, or timing tower slip. and proof of pump gas and not sunoco's 100 either
as seen as the guy toute'n the 305 reasoning was it be cheaper with a blown 305 over a bbc , I don't see how a 305 with blower(turbo cars suck to stage) and efi would be cheaper, than a basic bbc .
sometimes when chasing money going rounds the rule of K.I.S.S. is king.

vinniekq2 mathematically, you need a 340 hp engine with 7-8 PSI to make 500 hp,or 250 hp with 30 pounds boost.
Like Dave,I have no bones in this battle,but I really really would like to see a match race.

good luck. I'll tell ya now it's not gonna happen, with 2 mopar 2.2 turbo's at 450hp we needed 94+ 40% race fuel

A bad choice for the engine and power level desired. requires intercooling when driven at high rotor speed
and not compatable with a carb.

I know what blower to use on the S/C 305 combo , thanks. It will make well over 500hp on pump gas in a safe reliable state of tune. (I will also be using it on 350's) (550+HP)

1Gary You will see a number of Malibu's listed in here in the 10's running a BBC and glide.

The only reason sone cars use it is rules ( superstock)
The th350 3 speed always performs better in these cars too.

99.9% of cars that swap to a 3 speed from a glide run faster with the 3 speed.
More reliable longer engine life too. Remember this is a bracket car.
The glide is a bad choice on this car.

A 2 speed trans works well in a very light weight car with a very big CID engine
Like a supergas car 2300lbs 500+CID big block. When you copy what yousee on the pro classes and try to apply it to
a 11-12sec car that is a lot heavier and has a lot less engine power you end up with a snail.

These cars always run better with a 3 speed th350 trans.
Required combined first gear ratio.... to start..
This isn't a winnable discussion.All the wins I posted was with a SBC/glide.

tons of 3200-3300 lb cars running glides, and running with mighty fast 60 foot times
don't know where you where going with that comment..

as far as your 305, you'd be better/faster with a series III3800 s/c stock with a pulley change

1Gary Well I am going to respect you with a answer.I have for yrs been apart of a partnership that has always build cars that run well under the class number.And do so not to put a ton of stress on the engines we built.It is that to our credit we have a national win,a number of regional wins,and points wins.I will tell you there isn't a national winner found anywhere that isn't saving numbers in his package.Not one.So to try to be a internet hero has absolutely nothing to do with this build.

The other part of this is to be very sure not only to cover a ET,but have a package to cover the back haft of mph in a run.If I am to end up being the chase car,it is important,and yet still save numbers doing it easily.The other part is if I am not successful to slow the car down,I have laid the foundation for a upgrade to the next class ET having to change alittle,but not much.

When I say save numbers,I am saying that so not to do stupid unsafe smoking front tires in the lights.Never would put myself or any competitor in that kind of risk situation.

Also it allows me to run quick classes.

I think it puts tons on me as the driver.First at the tree,at how I run the laps,first to cross the stripe and run my dial.

That to me is having fun.No more worries about sponsors,the business aspect I have been having for a very long time.A retirement ride.
