377 or 350??!!

[Cristián]

Hello guys,

I don´t write very often in this forums but I read almost everyday.

The reason why I´m writing in this moment is because I´m on a big doubt; it´s about building my next engine. Current engine is a sbc 355 with flat top pistons, 3000-7000 crane cam, 64cc Camel Hump heads and some other goodies.

The original idea for the next engine was build a destroker sbc 377. I bought a forged 4340 Eagle crankshaft ready for this engine, 3.48 stroke and 2.65 main journal. Besides already have forged rods and pistons overbored to 4.155. The "little" problem is the block; the one a had bought was really bad, broke everywhere and impossible to fix (which would be a bad idea too). Found a new block seems to be the easiest way out, but here in my country (Chile) is really hard to find this kind of block, specially in good condition.

I´m so dissapointed for this issue that an idea came to my mind which is to buy new pistons, send the crank to take it to 2.45 main journal and build a killer 355 with this parts. Cylinder heads are going to be 58cc Aluminum wathever the engine be; the´re already on the way home.

Hope you can help me to decide what engine should I use. If one of yours has some experience with destroker 377 I´ll be glad to read your opinion, I´m kind of obsessed with that engine. But if it is not much superior to the 350, thats gonna have to be my decision.

Thanks a lot for your answer, this site rules!!

Cheers !!
