How street able are these 340 stroker motors?
Hey Dan , assuming you still have the block I built it would work perfect for a stroker with those W2s.
The block is a 71 360 and has already been tubed for roller lifters and has had the oil galleys drilled and reamed for better topend lubrication. 71 blocks were actually 340 cores machined for larger mains and 4" bores. ( correct me if I am wrong )...
Those heads have been mildly ported using MP porting templates , 2.08 intakes , bronze guides ,titanium retainers and super trick Norris stainless bushed rockers.
If you go with a 408+ stroker kit and a .550 range cam you should end up with more HP and torque , better idle ,lots of vacuum at idle and great streetability....
I would have built it that way originally but back in the 90s stroker kits were not readily available and quite expensive.
Not sure why you want to go back to a340 since no one can tell unless they look for the #s on the block.
Micheal, I received your email the other day but my internet is screwed up and i cant send emails.
your block is long gone, when the California kid popped the motor M&M cylinder heads in Cali swapped the block out for a 1978 model. Either the block was toast or they kept it once they seen all the machine work that was done inside it!
I think its just a rebuilt 1978 bottom end with a steel crank, I'll know more once i rip it out.
Here's the issue,
I have to pull that motor this winter for the following;
1) Fix a hole someone put in the firewall for air conditioning!
2) Install the missing heater box.
3) fix the passenger side inner fender, looks like someone used a torch to take out the UCA bushings and warped/burnt the inner fender.
4) Strengthen the K member and power steering box mount with welds.
5) Install power steering with a stage 3 firm feel box, 1.06 T bars, LCA reinforcement plates, sector support kit and tubular UCA.
6) Mock up the trans tunnel for the TR6060 six speed.
7) I HATE the solid roller cam/lifters! So while the motor is out I am changing the motor to a 340/416 stroker. I don't care when i get the motor back in but i have to do the other stuff. basically i only have to build the short block.
If i decide to use the X heads i will give you first grabs at the W2's.
Cheers.
