My .02 is stay away from spray and just search the web for an engine. I bought my 406 off of a guy on a chevelle forum for $2,000, and its been a 12.02 in the quarter. Nitrous is cool but you can find a pretty stout 350 for less most likely that will give you reliable hp without the chance of burning it up if you're not that experienced with tuning.

A friend dragged this Regal out of a field and raced the piss out of it for years!
150 shot is as much as it would take... valves would float before it could hurt it self so it was essentially bulletproof lol
He sold the car a while back but it is still on the road...
They also knew what they were doing with nitrous...
Just because it worked for them doesn't mean you couldn't blow up your motor on the 1st pass.

Are your plans to use it as a shot or off the throttle ? Well you'll want a wet kit an max you can really run without using race fuel is 150 HP, an yes people do run them without race fuel but the systems are based on a 350 SB an over 150 HP running on race fuel( high octane). Most kits come with different jet kits. Get a kit that jet size starts with a 50 HP jet to start with, because you have a 305 you'll get 45 HP roughly, if you ran a 400 SB you'd get 55 HP, of course l'm just guess the HP #.
Basically you'll be safe with a 75 HP jet using it as a hole shot. After giving it a shot check your plugs for color. To run it off your throttle you'll need an engine built for nitrous, so that puts you out ! 50 HP to 150 HP wet kit is what your looking for.
I had 2-250 wet kits on my Camaro but was to hard on the Car. Had a 125 kit on my Oldsmobile that ran off the throttle but blew out front windshield from flex, both cars run BB.
Now they just sit on shelf in the shop.
You don't have to run a electronic retarder on your engine as you don't have high compression.

Yea im gunna hit the button, by race fuel do you mean E85? i have plenty of E85 around he that i could use. The kit that i have in mind is a wet system, its called the CHEATER and comes with 150, 180, 210, and 250 shot.

$1400 would go a long way towards a 350 making 150 HP more than your current 305......on pump gas.....without the need for bottle fills ......or extra wiring fuel mods etc. After seeing what happens to 305s after being rodded without spray I'd never spray one. I'd be iffy about boosting one too

Hah if i blow it up all of these parts are compatible with the 350

Really !!

cant tell if you're excited or calling me dumb.

Gotta read between the lines.
With a used engine, its hard to say what it will handle. Even with a new one, theres just too many variables. So SAFE is the key word here.

A generally accepted range is 150-shot is considered doable on just about any engine. Mixture is key! Any kind of lean out and you will burn it up. Even if the engine survived a 250 shot in that video, it hammers the bearings too much and probably wont be very reliable over time. But a 150 shot is mild enough that you could just keep spraying it and most likely be OK for a long time to come.

If you think of a gen1 305/350 with about 300hp, you can beat on it all day long and it will last for years with plenty of abuse. Above about 400hp you need to inspect it regularly to make sure everything is in order. So if 300hp is very safe based on other engines, then a 150-shot on top of a 140hp 305 is about right.

The motor is essentially brand new, the first 20000 miles of this car was literally driven by a grandma and the other 2000 was driven from my grandpa.

Eh with what I'd be worried about letting go in the engine(pistons) might not be much left to reuse lol. Piston deaths are vicious lol

Race fuel means octane higher than you can get at a pump like 98, 100, 108 octane etc. E85 is not race fuel lol.

bone stock id still have the NOS kit and the carb, even if i do pull the motor and get a 350 id still need the carb and NOS kit.
