and I think your 305 is an awesome build cuz it's what hotrodin is all about. Taken what you already have and getting the best out of it to make yourself a mean machine. Makin lemonade outta lemons!

good stuff

Thanks lol, yeah i re-read what i typed, i meant to say "Just because it doesn't put 400 horses down doesn't mean it's not a good motor"*.

There is one thing that is bothering me about this engine build, the stroked and bored part, like i said i have TWO 305's, the one is stroked and bored, and i bought it with my monte carlo, and the other is a plain-jane 305, its where i got the 416 heads. Both bottom ends are in great shape, I'm thinking about using the plain 305 bottom end. I've looked into what it cost to stroke a 305 and there's no way to cut it, it's just not budget worthy, at all. It's at least 700$ to stoke and bore a 305.

why are you looking to use the plain 305 if you've got a good stroked 305?
... yeah, if you're looking to start from the plain 305, it's just not cost effective. At that point, it makes more sense to start from a 350.

Thanks 86Cutlass383SR. 😀
Yes, a 305 is not meant to be a FAST motor, but it can be a QUICK motor, for a good price. Just because it put 400 horses down doesn't mean it's not a good motor. And I'm not aiming for 400HP, not even close. I'm seeing what the best realistic power output out of a 305 is, without dumping money into it.

As for the flow charts there, yeah i plan on doing some of the minor porting work myself, nothing to serious, because I'm not that experienced with porting my own heads. But at least if i screw up its not that big of a loss. I figure if i can do some minor port work to these heads, then anybody here on this forum with some engine know-how can too.

Adam,
I love your aditude! I say go for it, say nay to the nay sayers. And even IF it goes over budget, hey you learned something doing it, and you taught us along the way!

I love this forum, cuz when it comes to respect, support, and incouragement of cookie ideas, this forum is so far beyond sites like thirdgen.org

Love that last sentence.......spot-on, IMO.

wow, good find...
this is neat stuff.

Alright, so today i started ripping into the stroked 305 (340) that i had, remember i didn't build this motor. It came with my Monte Carlo, and the block was the original block to my car, or so the casting says.

So i tore down the front of the motor, took off the carb/dist and all the linkage hookups. i pull the intake off, and there's a Spider retainer?? and at the same moment i looked down and noticed the cam button, then noticed the lifters have guides.

Why would someone put a hydraulic roller cam in a 305?? i guess they where trying to achieve something here. a 305's RPM range is pretty much determined by its bottom end, not by limitations of the cam style. So if someone went through the time effort and money to machine a 305 block to fit a hydraulic roller cam, i can't wait to dissect the bottom end and see what parts they used to stroke and bore it.

Nobody machined that block to accept the roller cam. With it using the spider, that means it is a factory roller block.
The casting number won't tell you what car it came from but the suffix code will. Casting number will only give you an idea of size and years it was used. The suffix code will tell you what exact year and vehicle it was in.I'm willing to bet it was originally a f-body engine, makes better sense since some of them were roller cam motors.

 

[CamaroAdam73]

Wow. I had no idea, i need to run the numbers on those heads again, if it's an F-body roller bottom end they could be vortec heads( center bolt down valve covers) and not the swirl pools. But the guy did say, the top end was from the monte, so they're prolly the junk swirl sh*ts, ported and fitted with bigger valves for the F-body bottom end stroked. Sounds like it was a decent engine combo, i wish i could've dynoed it.

 

[jrm81bu]

Vortecs only use 8 bolts to hold the intake instead of 12. The head choices would prolly be swirl ports from a tbi or maybe something a tad better if it was originally a tuned port motor. Now if it has the top end from the monte then it really doesn't matter.
Still a cool find for the roller cam though. Gives you some more options, but then it gets back to how much money is it worth putting into it.

 

[CamaroAdam73]

Yeah the stroked 305 bein an F-body bottom end kind've defeats the purpose of the build lol. Are the roller-cam 305's as easy to find as the 305's from our cars??
