Who is this guy pretending to be @Newbomb Turk and what has he done with the real Tim?
Tim takes a vacation once in awhile and the guy that fills in is not only nicer, but better looking too.

I haven't met him yet, I wonder if this guy is the wife's boyfriend he is always talking about, as long as the guy ain't messing with the dynoTim takes a vacation once in awhile and the guy that fills in is not only nicer, but better looking too.
Nah, Newbomb Turkey is Tim's nicer twin.I wonder if this guy is the wife's boyfriend

You can build hp with various ratios of basically duration to head flow, look at LS engines they build 450 hp with 218° cams, say OP hits his goal with his 230° cam as long he has decent gears and stall to go along with it shouldn't be fine.
Never said it was, but the basic principles are the same, a better head will generally need less cam to make similar power and out of everything cam plays one of the biggest role in driveability, so generally if looking for streetability building hp with head flow over duration gonna give better results was my point.No disrespect,,,,but the LS engine is a whole different animal .
That’s apples and oranges to a small block Mopar .
Those cathedral ports are nothing like a Mopar head,,,,,and are not a fair comparison .

I do believe that the start of a happy result for the 340 would be to go higher with the compression .
And I mean a true real compression,,,not a calculation of what it theoretically is .
A few CCs here and there can easily lower the real value a quarter point or more .
When people think they are running 10.5,,,they really only have about 10 to 1 .
Back in 69 when Chevy put out the 302,,,,that was a bad little dude .
And those pistons were ever so slightly short of 11 to 1 .
Heavy TRW pistons they were,,,,,but it was an evil little engine,,,in the right hands .
If Mopar had done that to the 340 in a beautiful little Dart,,,,,man,,,,you talk about some embarrassing times for Chevy and Ford .
A 68 or 69 Dart,,,with a 340 with 11 to 1,,,,solid cam with high .480-.490 lift.,,,,X heads,,,,good aluminum intake.
Then,, in front of an A833 4 speed and an 8 3/4 with 3.91 suregrip,,,,and super stock springs .
Oh yeah,,,,,,wild times for sure !
And that car would have sold,,,,,it would have been a contender for the win every time .
Ohh wellll .
That never happened,,,but I believe it is still possible to replicate .

Eat that Chevy boy!The night I ate up a 69 Camaro with a 302 in it I enjoyed every bite. Especially when the local Chevy builder told everyone I was dead meat. Lol. Beautiful car and I don’t remember ever seeing or hearing about it again other than how pissed off he was. Funny thing is my property borders the family farm so I kinda hope he can hear me loading up to go racing.

My best friend in high school had a 67 Z28 with a 302 4spd 4.56 , that car would rev to the moon, did fairly well for what it was.The 302 came out in 67, not 69

But no match for my 67 fastback with 383 torqueflite 4.57 .
Naw, he's buildin a 302 Chevy now.Did you guys scrap the 340 idea and go with a stock stroke 440 yet?
Or can we change pistons and spray it?
That is hilarious, thank you sir : DNaw, he's buildin a 302 Chevy now.
Yea they are, that was back in 78 or 79 when they could be bought for penniesDidn’t make many 67 Z’s(602 I think) they are worth serious bread.
I didn’t recommend KB pistons I just grabbed the very first post in the 11.20 area to show how easy 450 horsepower is to make. Unported Edelbrock heads too that flow 255-260cfm compared to 300
i have a client with a 67 RS Z28 302/4spd, which i understand is crazy rare. it's a super time capsule and a really cool car. total day two with keystone kustomags, lake wood slappers and hooker's. i don't know if it came with 4.11's or the PO did them along with the other stuff, but it was a serious piece. the guy had me swap in some 3.55's so he could drive it and enjoy it a little more.My best friend in high school had a 67 Z28 with a 302 4spd 4.56 , that car would rev to the moon, did fairly well for what it was.

That requires at least 1.32 HP per cubic inch, and while achieving that is possible, it's not going to have street manners. I suppose it's all relative to what you call street manners.
Build a 416" and you only need to make 1.08 HP per cubic inch.
