1995 suburban 8.1L swap?

[smithkid1996]

cheaper than a 8.1L would cost

well, i can build out the 8.1L for under 4000 no problem, not so sure about the 6.0L.

im asking if we can build the 6.0L for 4000 with more power then the 8.1L?

[T-Stark]

yes the engine is way more common than the 8.1, more common means cheaper parts. 6.0 is in trucks, cars, and suvs... more parts can interchange and be more efficient. cam and a built top end 6.0 will be in the mid 4s with a good tune and thats well under 4 grand.

yeah, im looking at replaceing all rods, berrings, rings, and gascets, along with TONS other DIY machining upgrades, top of the line ignition system, and a mild cam, cold air intake, oversized exhaust, lighter valve train deeper oil pan (if possible) and mayber a few other small things. i would LOVE a supercharger, but i think all of that plus a used engine will be expensive enough.

The 8.1 is perfect for what you want to do. But I think it will be much more pocket friendly to keep the 454. Rebuild it, do whatever changes you want to do, and convert it over to MPFI (Edelbrock used to make this setup, not sure if they still do) and carry on.

Basically, the 8.1 isn't worth the effort of the swap.

8.1s are perfect for boat anchors.

its a TBI454, there are NO performace parts AT ALL. it has only 230HP, thats just not going to work. to get the kind of power i want, it would be cheaper and WAY eisier to just swap the engine and be done. i have allready priced all of the parts. its just not worth keeping anything other then the block at most, but it would be cheaper to buy a used vortec engine, and rebuild it, then buy all of the parts to convert it to a vortec.
