Cleveland or a Modified??

[COBRA406]

Zoom,
If your number is D2AE-CA or E2AE-CA instead of 2EAE-CA then that
would designate your 72 or 82 year block. The early MCC (Michigan
Casting Center) blocks are prone to cracking in the lifter valley area as
previously noted, M blocks primarily. Good machinable Cleveland blocks,
(.030 over is generally max for performance engines) are becoming hard
to find. M blocks can be a decent performance bargain build, 400 only,
but lack of performance parts make this challenging. No decent intakes
are avail for 400s but spacer plates can be used with good Cleveland
intakes to make them run. Aftermarkets in both US and Australia are
now beginning to expand for these 335 series engines. They still can
make a ton of HP with those giant valve heads if a person knows what
they are doing. Aluminum heads are now avail from Edelbrock and from
Australia from CHI and AFD. Jon Kaase had a 408c win the Engine
Masters Challenge last year and smoked most of the other BBs.
THis engine has its minuses but they can rev and make tons of HP when
built properly. Not everyones cup of tea, though.
