Yeah I meant 351.....we also have a Windsor that the boys bored and stroked out to 427 or there abouts....never ran right so we rebuilt the 351 Cleveland and but a mildly hot cam in it and the carb/distributor/computer kit in it. The Windsor is s future project.
I read that 427 windsor is an absolute beast but yea, there are issues with them. At least their were last I read. Which was like 5 years ago.
I always like the Clevelands. Especially the 4Vs in the Ttorino/Mustangs. Tennis ball intake ports and 7K RPM out the door from Ford.
No sound on earth like a 351 Cleveland wound up tight. Chebby guys hated that sound. Especially in Doppler as it pulled away from them ;)
