i'm hoping to get my hands on a 92 white 25th anniversery edition with 305.
1. Plan 2 stroke it to 335
Good Bad?
2. Plan 2 supercharge it after
wise or unwise on a stroked 335...?

thanx fellas

Stroke it and toss in a 3.55 and posi.. Leave the super and toss in forged pistons and get a 125HP nost kit.... Cheaper, would run faster and be a lot of fun...

 

would it be possible to make car with a supercharged 335 (stroked 305) do a top speed of around 160-170mph (not drag racing)? what would be needed besides a prayer. also can we remove or adjust the governers on our cars? how?

 

I would say possible but not with an auto. My car has 3.73's and I think it would top out at like 110 or so. I think the 5 speed had better top end also.

3.73 gears out back
T-Tops and Black all over.

 

l'd say if youre more intersted in top speed don't stroke the motor first of all, that makes a ton of low end power, not really all that useful in the top end section. My idea would be to get your hands on a miniram or similar intake, do some serious head work, and a cam that has a top end power band (something useful from 2-7,500 RPMs) some large tube headers, and a good 2.73 gear matched with a 5 spd. trans. You don't really need to stroke it, nitrous and forged pistons would be great to help you get there. but something that breathes and runs quickest in the upper RPM ranges would be optimal. (a high reving motor)

good luck

 

as far as head work do you mean porting. Should i get factory or aftermarket heads? Keep the supercharger idea for added power across the power band. Don't our engines redline at around 6,500. I need help can anyone suggest a book.What i want is an engine that will pull nicely across it's power curve and take me to 170 (yes i'm changing the speedo.oh yeah it doesn't hve to beale to do more i just want to get thier if t has midly strong low end and dercnt mid range thats fine it can pokey real slow to 160-70 for all i care. why shouldn't i stroke it?

well as far as stroking it- in my opinion it would be a waste of money, especially to stroke a 305. if youre going to stroke it, just get your hands on a 350 block. Not only the money loss, but stroking a motor gives you a lot of bottom end torque, not really ideal for a high top end motor. if you were to stroke it, and run a cam thats quick from 2,000-7,000 RPMs you would really be defeating the purpose. also changing the cam changes the redline in case you didnt know. if you were to change the cam you would also need to change the entire valve train system to accomodate for a high reving high top end cam. the 305's got a 2 bolt main. if l were you l would look for a 350 with a 4 bolt. and as far as a power adder l would use nitrous instead of a blower, because nitrous is really quite a bit more useful through the entire powerband unlike a blower which is really more useful off the line. don't forget, when youre asking a car to pull that hard (160-170 MPH) you also have to upgrade the ignition system, fuel system, suspension, air baffles, tires, brakes, etc. etc. remember the HEI system begins to become quite weak at higher RPMs

 

maybe i'm over stepping my goals...ok i'll change the engine,cam, ingnition, fuel, suspension, etc....
as far as trans....
will a really good (raceprepped)automatic help me get to around 140-150

i wanted the super charger to make up for possibly a low bottom end the

i'm not a nitros fan i'd hate to refill bottles when ever i was just goofin around. and i've seen and heard good and bad stories about NOS.

i don't need the car to be a constant racer. just want to be able to push 140 if i feel the want......thanx for you help....more info please... can you suggest a book...?

well when you say "goofing around" its misleading- going 170 MPH is not really considered goofing around. its not easy to get a car up that fast and its even harder to keep it stable going 170 MPH. with a small block motor its really either one or the other. top end, or acceleration. you can't expect to run a 12 second 1/4 mile and also expect to go 170 MPH in the same car. and your question about the auto trans. if i were you I'd try and get in as many speeds as possible. the 6 speed out of a new SS would work really well

 

you have opened my eyes. Thank you...what kind of compromise can i make...i like decent top speed but i don't want a car that will get burned by rice on the lonely dark road...you've been being a great help. can i still expect a decent top end out of a car that does 12-13 in the 1/4? If so what kind. if not what kind? io just for reference i've decided to go with 350 tpi. i don't know about the charger and cam yet....thanx in advance i'd hate to start out in the wrong direction.

most of it depends on your rear end ratio, and money. I can run a 14 flat in the 1/4 with my TPI 305. i've got aftermarket runners, which give it a little more of a breath of air in the upper RPM's, an exhaust system by dynomax. gives it additional upper RPM breathing without sacraficing low end torque. I've got a 150 HP shot of nitrous and I've (for now) got 2.73's with posi traction. I (on nitrous) can turn a 14 flat on those 2.73 gears. also I can top out at around 140 MPH (l'm pretty sure) my speedo goes up to 110. but judging from the RPM's after the speedo needle bounces at 110, I'd say on nitrous I can hit close to 140 on nitrous, and the fact is I don't NEED nitrous to hit 140, it just gets me there quicker. moral of the story- I can run about 140 MPH without nitrous. I'd hit about 15 flat in the 1/4 without it, but with it (it's there whenever I want it remember) i can nail 14's flat and 140 MPH or so in a few seconds less. now imagine what I could do with a 6 spd trans rather than a 4 spd.
