I've also seen, just don't remember where it was, there is now a package out to stroke a 305 out to 340... With the right heads and valve train, could be interesting. I've done a couple Ford 347 strokers. They won't run with the 408's, but they do run strong!!!!Yesterday is history, tomorrow is a mystery, Live for Today!

How bout some parts and specs for those of us whom have 305s which need to be rebuilt?.
Education is expensive. Keep that in mind, and you'll never be terribly upset when a project goes awry.

441' heads with 1.94/1.6 valves.
Edelbrock performer intake.
Edelbrock 500 cfm carb part #EDE1803.
The Camaro had a 3.55 gear with 2,000 stall.
The engine was never on the dyno.
I would guess 275 hp.
Torque was very good.
The car would "light" the tires up under 20 mph very easily.
He also claims he is getting close to 20 mpg if he keeps his foot out of it.
I would guess closer to 17 mpg.
It was a good build.
Yes, you will have to clearance some of the rod bolts.

Thanks Eric, with my recent accumulation of Camaro's, got to save the part info, might be needing it!!!!Yesterday is history, tomorrow is a mystery, Live for Today!

I wonder what the dollar per HP ratio is for a stroked 305, there does not seem to be a great gain to be had from doing it.
Unless your are just dying to stroke a 305 and don't care how much it costs, there are much cheaper ways to go about making horse power.
It would seem better judgement to find a cheap 350 and spend the same rebuild money on a 383.

If you are wanting to stroke bore and buy heads pistons rods etc....I would look to the 350 block not the 305.The 305s strong point is cheap and plentiful,once you do the whole nine yards to it you loose the cheap part.At the end of the day you will have spent the same money on way less performance than a 350. Do not get me wrong I like the 305 and have a built one now,but with the money you want to spend it would work out way better to do this to a 350 after all you are only going to use the block from the 305 when its all said and done that will be the only piece you dont replace.Soo for a 100 more you could build a 383 after all you are buying a crank heads rods pistons etc.The value of the 305 is to utilize the crank rods pistons and heads etc you already have to keep the price down.
I would do a intake ,cam and header upgrade to the 305 and call it good,I would not spend all that cash on a 305,because unless you stick your head between the firewall and motor to see casting numbers you will not know its a 305 untill you want to race someone then you will know its a 305
The small bore on these blocks makes big hp numbers harder than a 4 inch bore block.Plus you can build the 350 and still drive around,then do the swap in one weekend and be driving again.You are looking at a minimal of 30 days down with machine work and ordering parts for the 305,because you cant really order pistons till the blocks bored and so on with the rest of the build.
Do what you like ,....but you will not be gettin the best value for your dollar and will have to tell everyone its a 305 because it will look just like my 383 that cost the same as your 305 stroker and will smoke your stroker motor big time!!!
You spent 50 bucks on 2 cases of beer and my guy gets me 6 cases for the same price ,...who you gunna want to get beer for ya ?.......Last edited by shawnlee28; 11-22-2006 at 01:13 PM.

I had about $3300 in a 377 (destroked 400). I can promise you your stroked 305 won't touch it in power and wouldn't be much cheaper. Most of that was machine work and aftermarket heads. I ran 11s with a full interior and a wore out 3.73 posi in a 86 monte ss (similar car)
read up on what the bore/stroke ratio and rod length do for power production and how they affect the rpm range its good forLast edited by 53sled; 11-22-2006 at 01:58 PM.

WOW!!! you must be making 650+ to only need a 3.73 in the 1/4 mile and run 11's.

Ok gang. It's been awhile. With everything that was going on taking care of my mom's affairs and making a few needed mods to the Healey, it was June before anything really got rolling on this...
