Blocks were built 20 years ago...he said they’ve come a long way since then.

I confirmed today that Alex Hledin built these motors! I've been texting with someone that works with Alex and it turns out they still have parts even though Alex hasn't built a 2.7 in 20 years! I found out that the welding on top of both blocks is because they had to open that area up so they could weld the block in the water cavity because the bigger sleeve went into the water cavity then they welded the block back up. The ECU chip is a custom curve Alex came up with but as RBT said it wasn't reliable. I was told to use a Champ ECU at full rich. The heads are from molds Alex made! The tube at the bottom of the block was put in for strength, they said these can make 400hp+

I'm going to ship both blocks up to Alex, who better to fix them!!!

Wow! Can't wait to hear more

Yeah, this just got very interesting.

I put something similar together a few years ago and tried carbing it. Pretty good exercise in futility and definitely should have went efi.

ALWAYS ALWAYS go EFI

[Capt.Insane-o]

Yea..i built it out of a 245 and didn't have a spare front at the time. Ran like a mf'r up until the carbs would say nope.

[Dave S]

So I am thinking... carbs are limited...as cfm.. oyer a common air box.....So how about 12 pack.... other than jettin issues?

[Dave S]

To all that.....know... the red book.... jennins.....yes to ports over ports......but it's a new world of..... I am sorry to say4strokemadness.....turbo or huffed.....the times are a changn.....MaxFrost....ntrooooppers.... shown my adg.... no my intleck...

They sometimes break thru where the sleeves from the opposing bank end at the bottom and cause a side to side crankcase leak.

The sleeves appear to be in crooked. High at the exhaust port and sunk below deck straight across. O-rings normally sit partially on the sleeve and partially on the register.
Digital pictures can be misleading, might want to check it out with a straight edge, before jumping off too deep in those blocks.

Growing up in South Florida, I've had to learn many languages ...
English, Spanglish, Ebonic's, Rasta, Haitian, and Bahamian .. so learning Dave S. is by far the simplest. Here is a quickie course ...
