A turbo can blow a stock 302.


Yet...you want this kid to invest in a 306 or 347? Why? So he can piss away his money that much faster when it goes BOOM?



Do your research before u commit to anything. Do not take 1 guys advice. Look at the guys that are actually doing it(not just saying they are)...pick their brains. Search message boards. And take everything with a grain of salt. Then form your own opinion. And buy your mods.

Its better to bore it over or atleast get supporting parts and spend more money now to make it as reliable as possible then just throwing the turbo on the stock 302 and blowing it up and then having to go back in and spend money on a motor when you could of made the motor strong enough in the beginning. the 306 kits with the 8.5:1 compression do really good with blowers or turbos. They're a kit the specifically made for running a blower or turbo

If you're looking for a less expensive turbo and want to run trins why not go remote mounted turbo?

So a bore or "supporting parts", will save the block? What about a stock block will cause it to blow? These motors are known to still be in great shape with high mileage. If u have problems, Ofcourse fix them. But if I say "turbo" and "stock"...I don't see the advantage of throwing money in the stock block.


I would rather turbo a stock block, cause I can get them cheap. If I'm going to invest in the block, I'm going to invest in a GOOD block. Not massaging over the stock block.

Turbos can make too much power, too easily, to justify spending money on a stock block shortblock that can not handle the hp reliably. Regardless of what crap you put inside of it.

If that works for u....great! But machining/cleaning a stock block for a 306, or 347, is a good chunk of change towards a good block. And you spend all that and you don't even fix the issues!

Anywho, different strokes different folks. It's your money!

I would never suggest anybody invest guts in a stock block and then turbo it. If you blow it up, you just destroyed those expensive guts too. The stock block is not strong, it's not a foundation for big power, and nothing will change that.

Big power the right way is also expensive, and there is no avoiding that.

If you want to make big power cheap, at least be honest about being cheap. You're rolling the dice.

So, if you're going to roll the dice, I would suggest leaving the block completely stock, and slapping on the turbo. If it blows, no money lost in the block, and the turbo setup will probably survive too.

to make good power with a stock block, go with a stock 351 windsor block.

Apparently my ex-husband made that mistake.

Eh, the difference in weight is negligible.

The stock roller 302 is ~ 155 lbs.

The sportsman 302 is 165 lbs. (+10)

The sportsman 351 is 184 lbs (+29)

Or how about the siamese bore 351 from ford racing at 157 lbs.
But it'll set you back $4200

The factory roller 351, which is considerably stronger than the factory roller 302, is something less than the sportsman 351 in weight difference. If you can afford a stronger block, get a stronger block. Saving 30 pounds is no reason to give up the strength.

I don't think so. You could claim some pounds for the wider lower intake plenum, maybe 5. But those items you mentioned, I doubt there's even a pound of extra weight.

Point is, worst case, we're talking about 50 extra pounds and heaps of extra potential.
