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

And they all are FOR SALE...Why? owner got bored... They all...every single one of them will run faster and quicker
and launch harder with a th350 in place of the glide. Real simple. And a lot more fun.

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)
500 out of a 305 with pump gas. I want to see this dyno sheet..
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

I don't have a dog in this fight, but even with a mediocre head and cam, an eBay chinesiem GT45 and a blow through 750, 500 crank HP is cake on a 305 and with a decent tune will live a long 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.

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.

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.

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.

I will have less in the whole motor combo, including the supercharger, than the BBC heads themselves cost.

One big benefit is I don't need to pay someone else to make my horsepower.

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

Not a problem with using stock size 1.94x 1.50 valves in the 350 heads, on a 305 engine. They don't touch the cylinder walls.

Whether the valve is in fact shrouded is a relative thing. Event hnou the larger 1.94" valve is closer to the cylinder wall than a smaller valve,,, It still flows a LOT MORE AIR than the stock as cast 305 head with its tiny 1.72" valves does.
The area where the intake valve is closest to the cylinder wall is a low flow area any way.
The air flow is concentrated towards the spark plug as it enters the chamber, not towards the cylinder wall, which would be a 90deg turn.

The 1.94 valve gives a net over all flow increase, especially if/when the head is ported. Shrouding is not a issue on this motor using a 1.94" valve. Valve to cylinder wall clearance is not a issue with the 1.94 valve. It is closer than the stock valve is but not a issue worth bothering with. No I will not be notching the cylinder bore.

But a 2.02 valve would be different.

No dyno test either. It is very simple straight forward low cost build. The car's performance will tell the tale.

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??.
