AJ's Opinion; Just for you 318 streeters

yada yada yada, my thread, my opinion, and go start your own thread, yur plugging mine up.

NO worries hater. I agree a bigger engine to start with is a good idea. I’m just trying to help those that want to hop up there 318, unlike yourself that pours hate on them small engines.

Interesting stuff....it made me think of the a video UTG did about a year ago called "the myth of displacement" or some such. Anyone know how to post a link? It ties right into this discussion

What UTG did is what AJ is explaining and why a bigger engine is better to do in a scientific manor. AJ gives outright good advice, except when he throws you under the bus for doing a 318.

yeah I'll bite
Above I had a 318 example with a 262* cam in an 8/1 engine having 535cc of Effective swept.
Lets see if I can match that with a 360. To get that, the effective stroke would need to be 2.598
Lets see, Hyup I get 360 cubes/800ft/ Effective stroke of 2.60@ 71.5* Intake closing angle, and check it out same VP of 99@ Scr of 8.9
So now, as to bottom end, these two are both operating as 261 cubers would at 100% stroke useage. And as you can imagine, with VPs of just 99 for both, both are dogs at low rpm, and in identical cars, will be identically doggy until that big cam in the 360 wakes up. I mean 71.5* is up there in the 284 to 288 range.

284/288 is a sizable camshaft in most every catalog. Not something I’d use in a streeter for everyday.

Well I don't know about anyone else but I found this thread a wealth of information from some very knowledgeable A-Body members! Me, I'm willing to bet, I am like a lot of members on here and don't have the technical knowledge of these posters, AJ, Yellow Rose, Rumble fish , 318 , but I'm sure glad to have your experience to draw from. You all have different opinions and that's cool. Please keep up the very informative posts. There's a lot more of us watching and learning than you may know.
This what makes a good community in my humble opinion.

Cheers guys !

Will do! I hope to help every small displacement guy that comes aboard looking for help without saying get a 340/360.

When a member comes on and says he has a 318 he wants to hop up, I try and answer them for there engine. I point to 318willrun pretty quick to! He is active on his you tube. (Maybe one day I’ll do one…lol!)

I started a thread over a decade ago on hopping up a 318. Things got in the way and the car had to go. I wanted to show a few things you could do and why somethings work better than others. It was fun for the short time I had it.
