But your Bio say's "trust me I'm a gynecologist".
I know we get a lot of "engine builders" on here.

doesn't building an engine mean you're an engine builder??

who cares if it actually runs when you're done.... thats for the mechanics to figure out

Were all experts hey? just trying to help

t i just seen a chevyhiperformance article on a vortec 406 build that had stock vortec heads with 1.94's/1.50,230/230dur. cam, the engine cranked out 425hp at 5000rpm and 525lbs tq at 3500rpms, which is very impressive and is what i'm kinda looking for, only i don't mind lower the torque and bit and increasing horses, i'm probably going to cut the heads for 2.02/1.60 and open up the intake and exhaust ports just a bit. i don't know if running more cam is such a good idea since heads are bit small, but what do you guys recommend? i know i can't run past 5500-6000rpm without running out of head.

before edit I,m finding that out,weve all seem to have done it. I see thesals has a drag van. I was feeling cocky one night in 69 whenl this van pulled next to my chevelle and whipped up on me like he owned me. I talked to him for a while and he showed me a mid mount Hemi inside it. That was very humbleing!

yeah thats the whole point of the van looks like a 69 econoline with a flamejob but its got a built 351w, 4 on the floor and 4.10s in the rear, 4 wheel discs and powersteering...... its an undercover rocket

Yea! The first thing I asked this guy was "How in the hell did you get that in there?" Had a buddy with a 68 or 69 ranchero plain jane, with a 428 CJ in it.That was a cool sleeper also! Did you have to build a new frame for it?

What you posted here is correct.
If you decide and install the larger valves I also would do a very good "bowl blend" and a gasket match like you said.
Intake wise I would run an intake like the Edelbrock RPM Performer with a gasket match to meet the heads,either a 600 or 670 vac. carb.
The 400's don't like as much ignition timing as a 350.
Start around 34-36 total timing and see how it reacts.
Don't forget to run a good fuel pump and you may want to up the dia. of your fuel line.
Run a 3.73 gear and a 2,800- 3,000 stall and you could waste a few of those new Mustangs, not that I condone street racing of any kind.L.O.L.

Now the hot tip is impound and confinscate your car /sell it ,and it lives to be impounded and sold another day.Each sale goes right into the state coffers ,again and again and again
