A good block to start with. I think it is the same block as the 351 Lightning & 351 Cobra R. Some one let me know if I am off.

351 Lightning
240 HP @ 4200 RPM
340 TQ @ 3200RPM

351 Cobra R
300 HP @ 4800 RPM
365 TQ @ 3750 RPM

I don't believe it's a roller cam block with bolt holes in lifter valley for spyder, but otherwise it's the same.

The 351 Lightning or 351 Cobra R had a roller cam? When I could not find any info to support this ? Where can I read more?

The 86 block is not a roller block.

The roller blocks are different fromt the non rollers in that the bores for the lifters are taller in the roller blocks.
There is actually more material in the lifter bore, which makes it taller in the lifter valley.

Drilling for the spider is secondary...


I don't know if ALL the Lightning blocks were roller or not.
Around 94 or so, all 351w blocks were rollers. There was a change made to the actual casting of the block to accomodate the taller roller lifters.
The roller blocks will have an 'F4' marking

I would definitely want a roller block for mine but I don't want to go the small base circle style either. I'm kinda hooked on the roller cams now.
