Need Help on Magnum 360/380 hp Crate Motor Tech Info

Badidea!
Very bad!
A 230 cam is about 276 advertised. In a 5.2 at barely 9/1 compression,these conspire to make a Dcr of about 7.3@142psi. Soggy soggy bottom end. You will for sure need that 3000TC. And don't try this with a 2.73 rear gears.
The power peak will be up around 5400, so forget the stock springs.The shift rpm with a regular ratio 904 will be about 6400.the stock springs will give up around IDK, guessing 4800.
The torque peak will be up around 4000, so yeah gears are a must. Ima thinking 3.91s or better.
With 2.73s the torque peak will not occur until 45mph, and the power peak not until after 60 and the shift speed is about 72mph; this all in first gear.Bad idea.
3.91s would reduce these numbers to 31/42/50
You want performance? Just go straight to 3.91s on the current engine and a 2800TC.Put some springs on the teener so it will pull 5000 and call it done! Those 3.91s will get you about 65 at 5000......at the top of second. Just about perfect for a weekend bomber.The 4bbl and headers will bring the current power level up by some 35 hp, but the torque peak will remain very little changed, so hang on!
If you are on a budget,this is the cheapest, easiest,quickest, way to lay rubber. If you are on a super tight budget, I would try it with the factory TC.
That 230 cam is gonna need gears and springs and a TC anyway, so you might as well start with those, Then,later, If the factory cam is no longer doing it for you, well then you will be ready for a cam, just not a 230*.That 230 wants 10 or 10.5 compression ratio to get rid of the soggy bottom end.
Shoot even the stock cam could use 9.4/9.5 Scr.
Oh yeah, the 750 will be too big in any case. With the 3.91s I would choose a 650DP type carb.
Ok so that's my opinion;"bad idea"

I must say tho with a 65 being some 350/400 pounds lighter than the later A's, it might not be quite as bad as I make it out to be; so if you're not looking for tire-shredding blast-off power, and if you're not against ripping it back out if it really is too soggy, and it's really cheap, well then; Go for it! But get the right springs to hit at least 6400rpm.BTW, the 230 will have great passing power with say those 3.91s,lol; 55 will be about 4300 in second gear.That's a rocket right there......and that gear is good to maybe 75 mph.......
As for me, I'm just getting lazy, and am no longer into doing things twice, or thrice or more ......like I used to be,lol.
