OH thank God. I didn't know you had another red truck. Here I've been thinking this rolled in a ditch all weekend.
 
So I have been missing my old Rusty 79 k30. Though I want to buy another truck Marty says I should just start driving this. The 6.2 was OK with turbo but I am a big block guy. Keep thinking 8.1 but keep the 465/syn 205. would like Hummer 37s eventually but the 235 85s will last awhile. Still want a rear locker but not sure what it takes on a 70hd. I will keep the auto locking Dana 60 till the hubs fail.
 
Why mess with an 8.1? Just buy a 454, toss in a cam and slap some fuel injection on. You won't be limited down the road with a gm Computer and bad head bolt design.

Then down the road you can put some real heads and stroker crank and will have a better 496 then a 8.1 could ever dream of being.

Plus the 8.1 block doesn't have a clutch provision in the block. So not sure if you ever put a hydro clutch in this truck?

I have no interest in aftermarket fi kits. I have seen too many struggle and go back to carbs. Not interested in building a real mp system for this. I have 2 or 3 454s in the garage to build but would want aftermarket heads and a hyd roller. Saving my gen vi for my Chevelle. I have a 8.1 in a Silverado and a mild tune brought out 40hp and 60ftlbs. With a cam and headers 400+hp and 550ftlbs should be easy. I have no 8.1 issues with head bolts, probably still fresh in it with forged pistons and ARP fasteners. I don't need a clutch ball with a 465, it is on the bell housing. I have plenty of hp in my Camaro, I just want a good trailer dragger and drunk farmer puller class winner.

I am talking about the head bolt pattern being different and not allowing the 8.1 block to accept aftermarket heads.
I'm not a dump truck transmission user so I don't pay attention to that stuff like the 465 bell. I just know that the 8.1 block doesn't have it.
I'm not talking about a sniper kit. But a real holley mfpi. Those setups don't have the problems like the snipers and fitech.
Sorry for replying john, I thought you liked horsepower and would want something more.

Oh I do and I will likely regret stuff. it maybe a bit so if I stumble on another GEN vi I will add afr 265s and see about a Holley or EFI. Don't be sorry, you know my mind is headed on one path but you never know.

but there is a 540 kit for 8.1s and dart and raylar heads that flow pretty good.
Yeah i know about the raylar 540 kit. Read a article that they put one in an avalanche and made 110 hp more at the real wheels.
Let me tell you I was IMPRESSED!. :rolleyes:

A 540 that can't even break the 500hp mark. Where do I sign up at?

I guess I just see so many going down the 8.1 path and I just don't get it.

I think they are fine for a stock truck with a tune or something like a basic driver and maybe a random weekend tow pig.
But when a stroker crank is 300 bucks.....i would never swap one. Just because they were the last big block doesn't mean they were the best.
