I did not state it clearly will but I was referring to the major car makers. I do not believe GM performance or SVO even make them. I would bet that 99%+ of all aluminum blocks in oval track racing are cast.

Ego you are a retard. He answered your DIRECT question. FWIW billet blocks are not legal in many classes/tracks in oval track.Comment

Stockcar5 the topic is about a GM CT525 crate motor, The fwdbite said he thought that they were cast and not billet. Look at the topic unless you are to stupid to figure out that I was talking about what the topic it is referring to.Comment

yes he did. and you didnt know who made billet blocks so you asked. you got a straight forward answer and it made you look stupid like usual. so you had to try and spin it to look less dumb. now you look even dumber yet...lol.Originally posted by Egoracing View Post

I thought that everyone could read with comprehension. Guess I was not thinking about you. If this was in a street stock forum and someone was speaking of a engine I would not recommend an aluminum large bore space block but then again I try to only post on the topic of discussion, Again common sense. The topic is the 525 crate engine which is produced by GM in there production facilities. Have you seen a production GM engine with a billet aluminum block which is what this topic is about.Comment

Very funny, really. So does anyone on here know whats possible with an actual CT525? Theoretically the stock block, crank and heads, whats safely economically possible power wise? Someone mentioned the oil system may be a weak link, so what kind of RPM's can she handle before oiling becomes an issue? Basically if I wanted to "Hop Up" a CT525 with the stock block, crank and heads whats doable??? I'm NOT looking for how I can cheat, just looking at it as a theoretical inexpensive all aluminum engine, thats it...Originally posted by dirty white boy View PostComment

800hp MAX, doubt you will get there without any power adders. But that would be my number. probably pushing at that with the sustained rpms we will see.
i think 700 at the flywheel would be doable if you were really smart. 650 should be easy.
Also, i havent seen any info on what valves are in these heads. Havent looked much, but they need to be replaced especially if they are the hollow stemmed.
7500 rpm max also without going dry sump. and I wouldnt venture past 7200 myself.Comment
