The 300hp 316ftlbs 4.3L 262

http://www.hotrod.com/articles/chevy-43l-262ci-v6-engine-build/ Awesome article, but what is the current pricing for such a build?

$369.97 Speed Pro LW2256-F-060, a lightweight forging (686 grams) with four valve reliefs with 6.1 cc of dish

$113.97 Sealed Power R9902-060

$?? Dougan’s Engine precision balance job

$50 Dougan’s was able to modify Milodon 190,000-psi rod bolts for a 350 application just by clearance the heads a bit

$40.97 Sealed Power tri-metal bearings PN 6-1020CP

$150 Milodon main studs and oil-pump stud were sourced from a V-8 application

$?? stock heads Dougan’s checked at 68cc chambers, pistons that we set at an average of 0.010 below deck

$50 Fel-Pro head gaskets with 0.041 compressed thickness 9.63:1 compression. Stock was 8.6:1

$?? we asked Dougan’s to mill a 3.475×0.060 dish in the pistons for a total volume of 12 cc, lowering the compression to 9.08:1

$50 modify Milodon 350 windage tray to fit the V-6. He cut a few inches off the front, enlarged one bolt hole (arrow) to clear the dipstick tube, and tweaked a few louvers to fit the stock oil pan

$50 and $23 Sealed Power part numbers 224-43469V (pump) and 224-14263 (pickup) 3/4-inch pickup tube

$11 oil-pump driveshaft is Sealed Power PN 224-6146E

$168 Pioneer balancer (PN 872021) on the right is a 6.125-inch, lightweight V-8 unit

$750 Comp Cams biggest hydraulic roller for our factory roller block, a 280HR with 224/224 duration at 0.050, 0.525 lift, and a 110-degree lobe-separation angle. The cam kit (PN K09-430-8) comes with cam, lifters, retainers, locks, seals, timing set, valvesprings, pushrods, guideplates, and rocker studs.

$97 Comp 987 springs

So our pick for a simple, budget, performance V-6 would be an ’85-’92 unit without a balance shaft, and we have a slight preference for the earlier units with perimeter-bolt valve covers. They just look better, and based on our inspection of junkyard heads, we suspect that the early ones flow better. But avoid the 200 and 229 heads, which have 1.84-inch intake valves. Speaking of heads, you’re sorta stuck with stockers. There was a time when GM Performance Parts had 23-degree, direct bolt-on performance heads and manifolds, but now only the hardcore 18-degree race heads and intakes are available; you can still get all kinds of iron and aluminum race blocks, too, including big-bore capability and priority-main oiling. We learned that Scat Crankshafts still has the very last few sets of Brodix 23-degree V-6 heads, but we were unable to find any others that are affordable.

$225 for 1318-12 Comp Cams 1.6: Pro Magnum rockers (PN 1301-12). Next time we’d use the new self-guided rockers (PN 1318-12) and omit the guideplates, as the V-6 heads had some pushrod-angle problems with the V-8-type guideplates.

$?? Brulio at Westech Performance hog the stock heads for increased flow. These heads are terrible, and even after porting, they only flow about as well as stock 305 Chevy heads.

$150 and $142 Milodon Megaflow swirl-polished, tulipped valves in 2.02/1.60 sizes (PNs 45015 and 45045), an upgrade over the stock 1.94/1.50s. Consider these steps mandatory to making any kind of decent power with your V-6.

$301, $817, and $90 MSD still makes even-fire (PN 8597) and odd-fire (PN 8596) Pro Billet distributors for the 90-degree V-6. We used an even-fire unit with MSD 8.5mm Heli-Core wires and a Digital-7 ignition box.

$264 Edelbrock Performer (PN 2111). This is a very low-rise intake, and we made best power with a 2-inch spacer from Wilson Manifolds($70 to $170 really?).

~$650 for a 650-cfm Mighty Demon w/ 2-inch carb-spacer

$4562.91 plus all machine work and your good block/heads/misc/etc. And there you have 300 hp and 316 lb-ft. with the ability to throw some boost/nitrous at it.
