i just found a small block in my woods im almost positive its a 305 or 350 (i just have a feeling) im working on getting it in my garage to rebuild and eventually put in a camaro now assuming the engines a 305 is it possible to make the kind of power to run low 13's to mid 12's (in a camaro) now im only 17 so as you can imagine id like to do this without nitrous or a super or turbocharger. i know some of you guys have a 305 camaro thats hauls *** what did you guys do to the 305?

 

Hey there, I am 17 also. And, as you might have noticed in my sig, I will be pushing near 300 hp and 350 lbs thru my 305. So ya, 13's is COMPLETELY possible w/out forced induction. All you need to do is hop the engine up a bit, get some WIDE ASSED meats, screw w/ your suspension (so you plant the torque better) and you will be WELL into the 13's/12's.

 

awesome , good to see someone my age on here my first mods for the small block are a intake manifold, carb, and cam i found a 750 holley already ne suggestions for cam and intake?

 

intake and exhaust are a GREAT start. So is a new carb. If it is already carb'd, then an aftermarket carb will help you greatly, but not 750cfm. That is WAY too much for a 305, and you will drowned it out. Keep the orig. Quadra Jet or go w/ something along the lines of 600-650cfm. The stock Q Jet will give you AWESEOME mileage. But a Holley or Edelbrock will yield you more power. Look for a manifold from Edelbrock, such as Performer, Performer RPM, and a few others. I cant remember the other names, chekc out edelbrock.com to find the rest of the series.

 

What the heck are you doing to get 300hp out of a 305? I'm not trying to be a d!ck, but it's extremely hard, if not impossible. If you're going to spend the money to build a motor, start with a 350. High 13's on the motor are tough with a 5.0L and mid to low are even harder to come by N/A. You'll just be disappointed. You can make a nice cruiser with a 305 but you'll be hard pressed to get those times. You'll need a good set of aftermarket heads, a good size cam, and enough machine work and small parts that will make it more economical to leave that block in the woods. If it's back there, someone put it there for a reason. Before you do anything you first need to find out if it's a 5.0 or 5.7L motor. Look on the drivers side of the block above the bellhousing and if it's a newer roller motor it will say 5.0 or 5.7L. If it's older you will find casing numbers that you'll have to look up on mortec.com to identify. Then you need to have a good machine shop check a few things before you go further. The block needs to be degreased and magnafluxed to check for cracks. Then the bores need to be mic'd to see if they're out of round and to see if it's been bored before. The line bore needs to be checked to see if the block is twisted. If it checks out OK, you'll spend 300-500 on block prep, you'll need to find a rotating assembly, a set of heads, cam, lifters, valvetrain, oil pan, timing cover, oil pump, and all kinds of other parts that would take too long to list. I think your best bet is to find a complete 350 out of a truck or something and start from there. You can pick them up for <300 at a junkyard or on the forums. You'll still need all the machine work, heads, cam and stuff like that, but you'll have a block, crank, rods, all the little bits and pieces and you'll know what you're starting with. Or you could always buy a crate motor for 3-4000$, stick it in the car and go. Sorry so long, but I don't want you to make a mistake.

 

my plans one day for a 305.....

enjoy!!

 

Oh ya.. the Performer Air Gap or RPM Air Gap are the other ones i couldn't remember. Those are REAL good.

 

nastyTA i can see your point for sure, but i think someone was gonna use it cuz its mated with a trans and everything looks pretty good but for sure ill have to get it checked

 

o, it's complete, then it may be worth it. Check it out.

 

yeah everythings there and its not seized up

 

i personally know someone with a 410 horse 305 TPI motor...hes runs a TPIS base, runners and plenum STOCK ported 083 heads and a SP-L98 cam (also TPIS)...and a set of 1 5/8 smoggger SLP headers...runs 12.2's on motor and 11.7 on a 90 shot...gotta know what your doing before you diss the little 305...just for fu(ks sake my VERY mild TPI 305 ran 14.12...only mods were a K&N filter flowmaster MUFFLER and the EGR walls ground down...

 

300 gross flywheel HP from a 305 is fairly simple. An aftermarket carb is not required. Nor is a RPM manifold.

My emissions-compliant version has demonstrated 250 rear wheel HP using drag strip performance, vehicle weight, and accepted conversion factors. Depending upon your favorite loss factors, that's at least 300 net flywheel HP. Desktop Dyno guessed 360 gross flywheel HP.

It hasn't acheived 13's because it's set up for street/highway and not the strip. More stall, more gear, drag tires, sea level air, it would easily be in the 13's. Non-emissions (more cam, open headers, etc.), probably 12's.

But, we'll probably never know. The car's my daily driver, so I'm not going to sacrifice that for a time slip. And, as you can see from the sig, a 350 shortblock is going in as well.

 

410 Horse!? Hot Damn Thats Amazing! Tell That Person You Know That I Salute Him!

 

I'm not here to get in a pissing contest with any of you. Just offering my opinions, experience and what I've come across. I think you'll find the consensus being that most don't want to mess with the 305, not saying it's junk or can't make power, just not worth it in most cases.

 

im still crossing my fingers hoping its a 350
