Power pack heads and it ran as strong as a 350. I once put a CC 268h in a 305 with 283 194 I noticed ZERO difference between it and the stock cam in the GM Target tmaster engine. On disassembly it turned out I merely had some bad rocker nuts that had backed off I thought my cam went flat so I ordered a 268h comp cams kit They pulled one of the expensive kits off the shelf!īasically they sell the same timing set but at different prices depending on how you look it up

I searched many applications and found 1966 chevelle ss 327 to be the cheapest AND it was adjustable for $25 !!! Oreillys had double roller timing sets with multiple keyways for around $50 and up It might be a factory RV cam as the G30 was a cutaway van RV conversion. I just made it 2 weeks on 20 gallons of gas- about 150% better than the 350 did It idles smooth as silk and has way more torque than the 350 did off idle but noticeably less upper rpm power. The 400 i don t know the specs but calculating for 1.5 rocker ratio It runs. It got 12 mpg city and highway but you put another truck in the tow dolly and it dropped to less than 4 mpg although it had bookoo power The 350 that overheated had the Edelbrock performer rpm I just installed a stock 400 from a 1977 G30 in my dually.
