I have a few concerns with the magnum. One is cracked heads everything iv read says the heads will be cracked and may need replaced. That's a huge concern. The intake is another factor more money.
I found a 360 out of a 92 truck 250 bucks that may be a better deal than the 75 318.
true, the magnum heads are prone to crack. BUT...… so many out there are at 250-300,000 and most likely have cracked heads. Under mild performance, don't seem to matter. Don't pull the heads and you'll never know :)
The '92 360 will have 308 heads, also prone to crack :) Roller cam motor, but still LA.
