Will The Supercharged Cadillac LSA Hit 800 HP? LSA 427 Build - Part 2 - Engine Power S3, E6

Take an old head bolt and cut a couple vertical grooves with a cutoff wheel and clean it up with a file, saves you a few bucks on buying a tap for cleaning the head bolt holes

[@bmstylee]

Interesting. That's an interesting way to do it. Saves you buying a set of taps which for good ones are not exactly inexpensive.

[@mgmjferg89]

Depends on where you are and where you get it from. If you buy a lot of cutters taps are inexpensive especially if you are just chasing threads.

[@207BigGameoutdoors]

I have been doing that for 15 years old a old farmer on my road growing up taught me and showed me how and also if you have a bearing race on a spindle or something where the race fits lose you can use a prick punch and hammer and punch the surface and the steel will rise up and mushroom and some time you can just do that to save a couple bucks if it is hard to find or get parts but I don't recommend it I lwas blessed to grow up with a bunch of old timers who were extremely smart with mechanics

[@andoletube]

He put new head studs in anyway, so whether he cleaned it out or not was irrelevant. If he was using headbolts, it would have been more relevant.

[@207BigGameoutdoors]

@@andoletube cleaning the threads on any head bolt or main cap bolt is always good practice and he was just explaining how to make a thread chaser from a old head bolt to chase the threads in the block for the new hardware without going and buying a new tap

[@anker5607]

Considering that the torque peak was at 2500, and didnt go below 700 until 6k, you could use this as an engine for a truck and it would do amazing.

[@mwaynem]

My thoughts exactly. This would make a great truck engine.

[@7071t6]

Should have put the magenson 2.3lt on it, then you will see so much charge cold air going in, instead of the 82 degrees temp, plus they dont show the temps at the manifold, which the LSA supercharger is not really efficient at all compared to the magenson IMO ? Plus they had a fan blowing at the intercooler heat exchanger and still had 82 degree hi temps? Cold air going into the combusting chamber is the key to all hp figures and the right fuel as well and proper flow in the head sure, but even stock LS7 heads will be just as good, it depends what your going to use the engine for street / drags or a every day driven car, would like to see the engine put in the Cadillac and just see what she does in the 1/4 with stock running gear ie: auto and diff gears, my guess would be around 10's if that?

@@bowhite1293 well think about it, if you put a stock ls3 376 cubic inchs camshaft in a 4.8 293 cubic inchs, the 293 sounds mean, but it's a stock ls3, so yeah a 427 would need a bigger cam then a stock motor

[@bowhite1293]

Correct. I was giving an actual degree amount of duration.

[@davidcunningham00]

@@bowhite1293 I'm kinda old school in this way, as I look how the torque carries a d where the horse power is at in the rpm range, I'm with you, I say if there is proper ptv I could see this thing going another 10 to 12 degrees of intake, and 12 to 14 on the exhaust

[@bowhite1293]

A 231/248 cam is in it for this build. Problem with going up a lot in cam is this build is already taxing the factory blower pretty good. A 1.9l blower on a 7.0 engine lol
