Force Posted May 26, 2014 Share Posted May 26, 2014 (edited) I know the "standard engine" in many of the Peterbilt 281/351, 282/352 trucks from that era was Cummins NHC 250 but there were other options as well, the NTA 370 might be one, Detroit Diesel 6-71, 8V-71 and 12V-71, possibly some Cat 1160 V8, 1673 I6, 1693 I6 and 1676 V8 found their way into some Pete's. I'm speculating a bit here but this question are for Tim Ahlborn, he would know for sure. Edited May 26, 2014 by Force Quote Link to comment Share on other sites More sharing options...

It's in another state and I tracked down the owner and gave him a phone call. I don't think he got what I was talking about but he gave me the info I was after. His particular 351 has a Nhc 250 cummins with rubber block Hendrickson and 5 spoke spider wheels. Ben Quote Link to comment Share on other sites More sharing options...
mistermodel Posted May 27, 2014 Share Posted May 27, 2014 335 cummins would of been a big power option.I recall something about high horse power cats needing an extra long hood compared to the "standard" long hood to fit a deep core rad.I guess cats needed more cooling Quote Link to comment Share on other sites More sharing options...
Force Posted May 27, 2014 Share Posted May 27, 2014 (edited) Yes...more power equals more heat so they need more cooling, that's the reason they abandoned the narrow nose trucks in the late 60's and did a wider hood so they could fit a wider radiator for better cooling. High horsepower engines from all suppliers often needed more room, for instance the Detroit 12V-71, Cat 1693 and Cummins KTA 600 as they are quite long and some are also taller than the less powerful engines.
