Problems with plenum.
1. what was described was not delivered, no bell mouthed runner, throttle body didnt fit, plenum sits too high to do a 3L conversion which I also asked if it would allow clearance to the bonnet for this.
2. welds were actually quite poor, some places looked like it was close to burning through, and I had it re welded to be safe.
3. i was originally told they would fit their plenum for $895 and do a ford throttle body for an extra $200 fitted. When I asked for a price for plenum and throttle body ready to bolt on (i am in a different state) the throttle body delivered was a second hand ford explorer one, it didnt fit on to the plenum (it was made to fit stock TB) and the TPS was the stock ford on/off affair.
Didnt really appear to be good value for money IMHO
PLUS
They did not deliver what was promised.
Bottom line, cut the top off your stock plenum chamber, weld up a new one with holes at the front for a new tb and radius the runners - $895.
I wanted a good plenum, I was expecting to pay up to $1500 new, so when mark told me how good his are I thought great, but bottom line is it would have been cheaper, quicker and easier and just as effective to have the throttle pos moved to the front and bored out the top of the runners myself - same difference.
