People have been calling to ask what the newly announced tariffs will mean for pricing and availability of parts. At this point we do not have a clear picture of how this will shake out, but we have started limiting estimates to parts in stock, and only providing pricing good for 7 days. We also have removed sale listings of some of our most popular products. Many of our suppliers have already notified us of pricing increases effective immediately….

Giving the Ford folks some Love, balancing up a 428" Small Block Ford using Mahle pistons, our own DMB Performance 6.250" H-Beam Power Adder connecting rods, and 4340 Forged crankshaft. Our combination uses Cleveland Main Journals, and SBC style Power Adder connecting rods with ARP bolts. With our new DMB Performance 220cc CNC ported SBF heads, this combination is going to make some of our SBC 427 customers nervous. (yes, our new SBF head flows more than the 220cc SBC head)

The numbers are in, and our new SBC CNC Ported 220cc Angle Plug cylinder head flows... 311 CFM @ .600 lift. This is not BS marketing numbers like many of our competitors use, but real 3rd party flow bench data from a well known cylinder head shop. These heads will be offered with 2.10/1.60 8mm stem stainless valves, 10 degree retainers, and solid roller springs good for .700 lift, + or - 260 degree duration for $1899 pair. This price is only for a limited time.

Can we fix up a very hurt Dart Little M block for our customer? We can sure give it a try... Lesson here, make sure you have your spiro locks fully seated, correctly, so this does not happen to you. Just a few seconds checking them can be the difference in a $6000+ Little M Block, yes, Dart, just raised prices again. Check back later to see if we repaired the block successfully.
