In your opinions what is the best main cap upgrade?

I`m getting into a 421 cuin W build and will be doing a 4 bolt conversion on my 71 block, i wont be buying the cheap caps but dont want a set that would warrant buying an aftermarket block instead.

I wont be turning over 7500rpm, will be all forged internals with a dish top my setup will be 11:1cr, will still be EFI also.

The main point to this post is the best quality caps for around 200$ since the line bore and drill and tap will cost me about 425$

Thanks in advance for your usefull input!

I have a friend with a similar setup as to what i`ll be using but he went flat-top and he is about 12.6:1 with a solid cam, it`s in a mud truck so he used a 2 bolt main and has not had an issue but 300ft a pass it dosent matter much, mine will be a DD as i always have with a bit of nitrous when needed, that is the need for the cap conversion.....

 

So i take it noone using a 351w has done the 4 bolt conversion then?

 

No one looks in the 351 section. Haha
