I have an early T10 and need a 5-bolt block which is limiting. Good for authentic discussion however limiting with engine choice. Hindsight being 20/20 I would have went toploader or later T10 as 289/302's with 6-bolt block are easier to come by.

Best in your decision...

Jeff,

Thanks for the info ...

Good point on the 5 bolt vs 6 bolt 289 blocks, I read about the differences and I would definitely go for a 6 bolt block and have more transmission choices.

Initially I was focussed on having a 289 and am still considering that option. The other way I may go, is to start with a new 302 block & crank, select some good heads and leave it at 'just' 302 cu in. With the proper carb, intake manifold and cam, it should make decent power.

My understanding is that aside from casting numbers, the only major difference between a 289 block and 302 block is the skirt length. If that is the case, then I suppose with a 289 crank and a 302 block one could have a 289 that way as well.

Just curious ... but are 'new' 289 cranks available?
