Default Lingenfelter Ad

I just noticed a Lingenfelter ad at the top of the forum page that had two lines of text:
"available now: 550hp 427 cid"
"LS1 $19,995.00"
(or something like that)

Maybe I misunderstood the ad, but how can a 427 be an LS1? Or are they two separate products from Lingenfelter?

To get a LS1 to be a 427 you need to bore the cylinder making them oversized then you need to increase the pistons total travel(stroke length) by change the crankshaft.

the engine is an LS1 with a stroker crankshaft bringing the 346 inch engine to 427 cubes by altering its original stroke

Pretty close, but I think that 427 has a resleeved block to get the bigger bore. Before the resleeved blocks were available, you had to use a C5R block, which the LPE twin turbo still uses.

Correct on the resleeved!

I have one (Darton sleeved) from 21st Century (LPE). It is great.

My S/O went with 21st Century LPE's heads, cam, underpully, Kooks headers, LUK clutch and alum flywheel, BORLA's, etc. package.

NOTE the price: $5950!!!! For 434 RWHP, and that's with 4:10's and a dyno day of 103 degrees, that is a STEAL!

If it only costs in the price range of 6k from other companies why does "L" charge so much.

The 6k figure is for just a H/C setup. The 20k is an entire engine assy., not just a H/C.

I'm holding out for the $26K Katech C5R engine. I only have $26K more to save up, too.

As another member posted, the difference is a complete engine (427) vs heads, cam, headers, clutch, exhaust, underpully, etc. on your existing block.

For the money, the 21st Century LPE $5950 offering for the above is a great deal.

at least IMO and from others that have posted their satisfaction with this package.
