Ok, right when I am deciding to sell my Scat 400 crank, I run over the fact that this can be used in my 305.

1. What displacement will this come out to be without overboring?

2. Will my Scat 400 cast crank 1 peice rear main seal work for this project planned?

3. Will I need tro buy pistons, rods, or anything else. What about machining crank journals or anything? I dont know?

4. I also have some vortec heads in my posession, will these work for a good combo.

5. Do you think I could break 350 hp with this 305 stroker, vortec heads, fairly mild cam, edlebrock intake, and a 600 carb, headers, and exhaust?

Thanks sorry, for the questions, I got temporarily hyped. Please fill me in. Thanks,

 

 

Ooh, ooh, Ill be the first to say it. Why not just get a 350? Seriously, cheaper, but I guess the uniqueness is cool. I have yet to hear of anyone on this board saying its worth it to stroke a 305.

 

Displacement would be ~329 cid (bore 3.736", stroke 3.75" - just calculate the volume of a cylinder from that data and multiply by 8 cylinders).

I've never seen stock-bore 305 stroker pistons offered. But, don't see many .030"-over 305 stroker kits, either.

Since it's possible to get 350 crank HP out of a 305, shouldn't be too difficult to get it out of a 329-334 with the same modifications.

 

Thanks for the input guys. Yeah, I am in a turmoil here. I have got a 350 4 bolt main lock, and some pistons. But, I ran out of money, and the block needs to go 0.060 over, and I think it needs some journal work. I dunno. Plus I still need rods, and a lower intake if I am going to put on those vortecs. I really wanted that 388 motor, but plans fell through. I was just trying to realize other options. Thanks again guys,

I'm sure it would cost you much, much less to rebuild that 350 shortblock than it would to put together a 305 stroker, even if you already have the crank. Wouldn't be surprised if the crank balancing wouldn't work quite right with 305 stroker stuff, either. The 350 will make more power when done, so selling the Scat crank and using the proceeds to rebuild the 350 makes a lot of sense.

 

Im startin to come around. Well see what turns out. But either thing I do do, one thing is true.... I NEED POSITRACTION!!! Thanks guys,

I think that above post is funny. I planned on doing the same combo (305 + 0.030 + 400 crank) and in all the books I had looked in for pistons, I had to order them for a 334.?? which I rounded up to a 335. Now I dunno what kind of calculating you are doing, but I am highly doubting a machine shop's book on what pistons they can order is wrong, nor a well known machine shop.

Not trying to be a dick, but still... I went on this same path. I believe I stil have the pistons sitting up there.

As for the nobody ever condoning a 305 stroker.... I do. I was gunna do it to have bragging rights when I would keep up with 350's and bigger. But then I realized... you are dumping a lot of money to stroke a motor.... why not just stroke something bigger. Same money... more cubes. NO substitute for them. Plus a 355 would be cheaper, and can more easily pull more horse than a 305 stroker motor.

If you really wanna get radical... go 400 and stroke it to like a 455

heh... too much stroking goin on here... Im goin to look at ****.

305 STROKER KIT
Chevy 305 to 335 stroker kit featured in Super Chevy March ‘99 issue. Our 305 stroker kit was installed in their Silver Streak project Car. This Exclusive Stroker Kit $599 added apprx. 95 H.P. w/carb and apprx.115 H.P. w/F.I.



its on that site the kid above me just posted.... check it out


HA!



:hail: :hail: *ME*:hail: :hail:

 

I dont really understand what you are saying in your posts, but...

305 bore=3.736"
Stroke=3.75" (400 crank)
PI=3.14159265......
Volume of a cylinder=PI*r^2*h, h in our case is the stroke.
There are 8 cylinders, so you have to multiply the volume of the cylinders by 8.
3.14159265*(3.736/2)^2*3.75*8=..... 328.8704641, or 329CI if you want to round up. At .030 over its 334.1733154. 334CI.

There's a hundred ways to skin a cat. My friend built one in 1986 by using a 400 crank and 400 rods and the stock pistons. Most people anymore dont bother with the 400 rods but 5.7" 305 or 350 rods, hence all the different pistons for "334" CI engines that people are using.

 

HAHA!

Good sites, thanks.

 

Oh geez... Not Crack Echo's site again

There are more mistakes on that website than there are in a Ford.

 

Yeah you see that "adds 95 HP BS" tossed around alot... of course, that's not what the stroker kit added. That's what the kit, the heads, the cam, the carb, the exhaust, and everything else added.

It comes down to $$$ per HP. You can take your "free", "paid for", "already have it" or whatever 305, spend $600 on this kit, and then machine a block for it. Or, you can go out and buy a junk 350, do exactly the same machine work to it for exactly the same money as the 334 kit would take, buy regular 350 pistons and refresh the 350 crank & rods. So that's $600 one way, or $150 plus a crank grind plus rod recon the other way. The 334 way you have to do a whole bunch of clearance work, all sorts of other hassles, buy a balancer and flex plate or flywheel, etc.; the 350, you re-use what you have. The 50 way you end up with a 355; the 334 way you end up with 19 less CID, and an inferior bore/stroke ratio to boot. More money, more maze to run, less cheese at the end.

You do the math. Any way I slice it, the 334 makes no sense. I can't come up with a scenario where it's the better choice no matter how hard I try.

And I also find Black Echo's monkey-spank nothing more valuable than a few minutes of amusement.
