318 upgrades questions
My plan is get the motor done first and then get what i need to handle it and as of right now the motor isn't done it needs a carb and intake once the motor is done i will go to the rear end and get what it needs
Right. The point in bringing up the head casting numbers as significant is because the 302s don't flow well compared to 360 heads. You're stepping into a zone where flow will be very important and those 318 port heads aren't going to be ideal if that's what you have. Sure, they're fine for a little .450 lift spin-off of the 360 2 barrel cam but for the cam you got there'll be much better choices.
You've been told what people thought the best intake was- the RPM Air Gap. They're not cheap but the cheap Performer will be worse for this app than a stock 360 truck intake. So if you're gonna try to skimp, buy a $10 iron intake not a $75 aluminum 318 intake.
What's more, since you've got such a high goal on your cam- little places you skimp will see big power losses. The stock converter will hurt bad on top of the drivability. 318 log manifolds will severely limit power as the 318 port heads likely will also. It'll require more money to make it work well than to buy a better suited cam and not have to change all that immediately.
Been told from people i know and trust one being the person i got the cam from that it'll work just fine even the guy boring out the block and work on on the heads said it'll be fine as long as i have the right gears in the rear end
As has everyone here. They've also told you make sure you have the right converter, a good intake, good heads, and good exhaust.
From what I've seen- your goals and that cam don't line up. It won't be quick without lots of gear in it and a good converter. It'd be better suited to a bracket car than a punch it and go quickly street car that's not geared toward racing.
Fully port the 302 head with 2.02/1.60 valves to match the bigger 340/360 ports OR...
Purchase Edelbrock heads and the. Have a machinist look it over.
The cost is close to the same when all is said and done.

This is an important statement too. Even in iron heads there are some seriously good heads that can be extremely difficult to match the flow of for the price redoing stockers.
