SMALL BLOCK HEADS

So, what I did not get out of your speech in the original post is where all the energy is going? I just watched Uncle Tony and his explanations of the reason (planned or un-planned) why small block heads are actually really good heads. Nothing about intake or nothing about flow numbers - but in typical UTG he explains in a basic for the masses. Something I totally appreciate.

He is a MoPar guy for sure and comes off as a regular guy with some skills. But you went in depth- really in-depth. I’m sure if you connected with him on here (he is on here) you could debate deeper than what he is showing here. Honestly I’m glad you are proving a point- I’m just not sure that point is needing to be proved. I am not as versed in head flow numbers as you are so I am not picking a fight. My end question is do you think the Mopar small block head is junk or really good? I’m a tad confused.

this post is not about intake its about exhaust. the intake is more important then the exhaust is for performance.(within reason). thats why i bring it up if it was just exhaust and that was it then leave a 2 barrel on your 318 and your good to go. flow numbers are a response to someone in my opinion is trying to get a gotcha moment. the energy is that the exhaust is not the reason for sbm being such a great engine. this is misleading and when you dont go into detail on certain subjects it leave people making mistake on there build or reasoning on other subjects incorrectly. this does not help. i dont mind basic explanations but this one is ridicules if you care about whats really going on in your engine. If your stuck with a certain size engine then all the things around it become very important like heads. if you dont have a good intake port you are going nowhere period. What if you were a young person starting out in the hobby and you saw this vid, might you get the idea that you need to look at exhaust flow number to decide what platform to start with. there are so many reasons why a 340-360 are the killer that they are. crappy exhaust doesn't help but the intake is what make a engine a legend. thats why hemis run like they do. his claim is the exhaust is awesome for a strange reason. This is why i want to clarify. You said "I’m just not sure that point is needing to be proved". this is why i started my thread with, I shouldn't do this but i cant help myself. but i think the deeper you dive and more versed you get, the better you are at your craft and its for those reason i really strive for whats really going on.
as far as mopar heads, there awesome. 272 318 heads out perform considering there valve and port volume on intake and exhaust. but thats not racing. 340 360 heads are good heads, thats the heads used in NHRA G/stock running 340 heads up against 396 chevys. last time i looked 340 had the record. thats some good heads to make that happen. if you tickle a 340 port with a die grinder they respond. Im not the best porting guy in the world but with a 2.02 valve ive gotten 273 CFM numbers. best ive gotten from a 2.02 fuelie head was 252 and mopar w2s ive gotten 308. the chevy bowtie heads best i could do was 271 with a 2.02 valve thats a ton of work to get there but it can be done. after market heads are the way to go these days for many reasons but money and flow are the main reason. if your going to go stock mopars are some of the best. but it helps to know what your working with to get the bang for the buck out of the pieces you decide to use. good luck be safe.
