New info on Len Williams Pontiac "crate" engines

For some time on this forum, folks have mentioned/recommended Pontiac "crate" engines from Len Williams but it seems no one could say that they had gotten one or could cite someone else who'd gotten one. Consequently, they got criticized for recommending something they had no experience with.

On the PY forum, there is a thread as of today from a guy who actually bought a Len Williams engine and is very happy with it. As a result, another guy chimed in citing his very positive experience with his Len Williams engine. There are many Pontiac engine builders out there like Butler and Sandoval who have Pontiac crate engines that are quality and a tad pricey. Reason Len Williams gets mentioned is the reasonable prices he has. But is he quality? Check out this thread......

No, I do NOT have any connection with with Mr. Williams...but am operating on a budget as are many others, so wanted to share some info on lower cost crate engine options for Pontiacs.

Thanks for posting that info !

According to his website, he's been building Pontiac engines since 1977. I first learned of him from the regular ads he ran in one of the Pontiac magazines.

If he wasn't a decent builder, I don't think he'd still be in business. He would have been crucified on all the Pontiac forums.

Ok, I see good info on Len Williams, and his prices are reasonable.

But has anyone heard of DCI Motorsports, or Carolina Machine Engines. They both seem to have comparable prices.
CME can sell a 400 HP 400 for 4995 (complete engine, not short/long block).
DCI did a premium stock rebuild on a 455, and quoted 5500 if I have a good core to start with.

I'm asking because I don't know. I see through this thread that Len is great. But I can't find much about CME or DCI. Any info would be greatly appreciated.

Don Johnston, at DCI, is a very well respected Pontiac engine builder. There has been lots of online buzz about his alum RA5 heads.

Since Len's online price includes all the core parts, his prices are lower than DCI prices. There are a lot of options that can determine the value of each build. Stuff like SS valves, premium pistons with floating pins, H-beam rods, type/brand cam/lifters, crank, etc.

I don't have a clue what is included in a DCI $5500 engine.

I have never used Len William's services, but have heard nothing but praise and good results from Pontiac people for the past 10-15 years. His engines seem to be mild performance 455's that live a long time in cars driven on the street. Certainly appears to be a great product at a fair price. Thanks for the post!
