You can lead an inbred to some words but you can't make her understand them. LOL

take a boss 302 in 1969 trim. 2.25" intake valves, 1.77" exhaust valves. 275cfm intake flow, whatever the exhaust was.....there are no rpm limits for a boss 302 block. its not a cleveland or a windsor block. its all its own...
build the bottom end with unlimited rotating parts....forged crank, billet i beams, 2618 pistons..... the heads had screw in studs so any valvetrain.
with flow like they came with untouched it is greater than most big blocks of that era. 275cfm vs big block chevy rectangular port l88 315 cfm.
so give the motor it's due and cam it to 305 degrees duration @.050 in a solid fla tappet cam. use a tunnel ram and a single 800 cfm carb. spin it to 8,000-10,000 rpms. 7100 was stock rpms with just headers considering the stock solid flat tappet cam it had.
that little 302 is a bad bitch. when i was a younger man, there was a few motors nobody questioned as the king of the streets for small blocks....
a BOSS351, 351CJ, and a boss 302. i remember boss motors in 4wd trucks spinning all 4 35 inch tires.this is in the early 80's.
i built chevrolets for customers. there are far more of them. and when i ported heads for them and port matched them, they were incredible. 340 or 360 dodge was another great motor with enough cam.
but the king was any BOSS motor.
Hio, you are right. few and far between. Ford has always made a few fast cars, and mostly ****.
the new 7.3 pushrod ford has 450hp and 600+ lb-ft. ford trucks only. such a waste and as usual Ford.

where most of you LS guys lose your way is the intake manifold....
you try to get cute with fancy this and fancy that.
a tunnel ram MATCHED to the rpm band makes as much torque as anything, but outpowers everything. a tunnel ram has VERY long runners, yep long... and have good helmholz characteristics. 2nd order to be specific.
but guess what. a long runner CAN make better high rpm horsepower if it has a taper degree designed for a specific rpm peak. its a lost art. oh, and all of you who like the curved runners of these modern fast or whatever?
lol. how do those intake deal with laminar flow? ask mamo. ask the gurus. they dont. the short side and the long sode move at the same speed. so...the long side tries to pull the short side away from the port wall.
you cannot have laminar flow in a curved runner. it is the reason all of these modern ports flow so well. its not just port volume and average cross section....

the msd for the LTx is a good on IMO, but still not a tunnel ram.
i read that manifold test for the LS and its as expected. a tunnel ram won, but it's a generic ram. to work right the taper is engine specific.
ULTRA-Z...u wanna win? save up and get a tunnel ram manifold designed for your combo. the velocity MIGHT push supersonic choke in stock ports, but up to that point it will do more than outflow.
you need to make the FIRST pressure drop at the choke point of your intake port. call hogans. long runner for torque and taper to FORCE flow. call them.

The problem with what you're saying is there was rpm limits for the 30p00 furd in that era. This is why a solid midrange motor won. To be honest the comparison snake posted is the lowest hp dyno ive ever seen out of a 302 chevy to. It also didn't have the 2 4bbrl crossram intake on it either.

she is doing ultrasound program. The last couple semesters she’s in now are 5 days a week clinical and classes. She might pick up a Saturday here and their at her old job. Which is like 13 bucks an hour. She makes basically nothing right now.
i make an extra 10-20 on the side tax free mechanic work so I probably make closer to 80. But yeah it’s rough right now. After my truck is paid off and she gets a job I will be pretty well off
she has mentioned me co-signing but I steered her to her mom lol.
i put a decent amount down on both vehicles and house payment isn’t terrible. I’m getting by but I’m slipping a bit. I’m not gonna end up broke and way in debt
