Monte72Carlo Posted April 3, 2012 Share Posted April 3, 2012 Hey guys, Today was the big day, I was able to bring home my new engine for the monte. I have liked how others such as davey have done engine build threads of the tear down and re-assembly of their high performance engines sharing tips and tricks. I figured I would do the same for my engine maybe sparking some more threads and sharing some knowledge. Anyways we should start with the engine keeping in mind this is for my 72 Monte carlo racecar which is heading in for a cage and some primer in the next few months or so as money allows. The engine is a 400 sbc estimated at 700 hp or so says the previous owner. We will put that to the test with a dyno run once it has been re-assembled with a few things here and there Engine as it arrives in the shop today: As I tear down the engine tonight I will post some more pictures and descriptions of the engine. Thanks, Garrett. Quote Link to comment Share on other sites More sharing options...
Monte72Carlo Posted April 4, 2012 Author Share Posted April 4, 2012 Engine tear down from last night: Bottom End, Bowtie Block Crank Trigger and jesel timing belt Jim Bell aluminum 18 degree ex-prostock heads filled with titanium valves Jesel Shaft Mount Rockers Big springs hiding an impossible to get to head bolt Rockers off waiting for my Moroso jesel shaft mount rocker spring compressor tool inorder to get at the last head bolt Lifter valley. Lifter band unknown as of so far. Looks kinda like isky tie bars. That wraps up yesterdays work, waiting on a backordered tool. Thanks, Garrett.

72 LS5 Posted April 4, 2012 Share Posted April 4, 2012 That's a serious powerplant you got there! What cam plans do you have for it? Bummer about that head bolt......... Quote Link to comment Share on other sites More sharing options...
CrazyDavey Posted April 4, 2012 Share Posted April 4, 2012 Hey Garrett, good to hear from you, this is a great and interesting post, please keep it going....that motor has some serious pieces in it, 700 maybe not be too far off. What is you plan for it, freshen, complete rebuild...etc...let me know if I can be of any help....Davey.... Quote Link to comment Share on other sites More sharing options...
dbreese Posted April 5, 2012 Share Posted April 5, 2012 That is a BAD mouse motor right there! Will be interesting to see the tear down and build up. Keep us posted David Quote Link to comment Share on other sites More sharing options...
Monte72Carlo Posted April 5, 2012 Author Share Posted April 5, 2012 Hey guys, Got the hidden head bolt off today and took the heads off. Flat top pistons with these heads at 32cc should be somewhere around 15-1 compression. I haven't done the math but I will come re-assembly. Cooper head gaskets! The plan for the engine will be freshen as well as rod change. Aluminum rods wont carry me far on the street and have a few passes on them already. Oliver rods most likely, I dunno yet. I need to talk to snow performance on a water-meth plate in order to bring the octane rating down and reduce detonation. They state one tank on water-meth I figure 4 liters or so lasts an entire tank. Who knows. I plan on in the future adding a direct port nitrous system of 150-200 shot. As well as a vacuum pump to the motor. The car of course will need a few upgrades itself to accommodate The old car of 2800 pounds ran a best of 9.40 with this engine. More pictures with tear-down. Thanks, Garrett. Quote Link to comment Share on other sites More sharing options...
Mike 57 Posted April 5, 2012 Share Posted April 5, 2012 Should be one heck of a small block! Looks like a set BIG port 18 degree heads. Should be a screamer! Do you think you may have trouble with balancing the crank when replacing the aluminum rods with steel rods. Once the crank has been balanced for a light assembly enough weight has been removed that you may have to get into mallory metal to balance the crank. You may want to talk to Bill Miller at BME he says that his aluminum rods are streetable. Looks like a fun build. Quote Link to comment Share on other sites More sharing options...
Monte72Carlo Posted April 5, 2012 Author Share Posted April 5, 2012 Yea thanks, I was reading all about BME previously. But there is still so much controversy over weather or not they can handle the street cycling. I Might give them a call and see if they can guarantee them or something of the sort. Thanks, Garrett.

Mike 57 Posted April 5, 2012 Share Posted April 5, 2012 I will be honest Garrett, those heads and available intakes for 18 degree heads will not be very streetable. It will be a great track motor, and a fun build. Quote Link to comment Share on other sites More sharing options...
Monte72Carlo Posted April 5, 2012 Author Share Posted April 5, 2012 I do know, But I want to be able to drive it to car shows, cruises ect.. Quote Link to comment Share on other sites More sharing options...
LostnFound Posted April 5, 2012 Share Posted April 5, 2012 That will make one heck of a grocery getter Garrett. You planning on putting wings on it? WOW! Keep posting progress please. I don't have the knowledge to do such a project but I do understand a lot of it and therefore I appreciate the effort that goes in to a build like that.
