Thread: 1979 350 Chevy Build ?

Tweet

I picked up these heads for my 1979 350 4 Bolt build today that's the blue one . They are #083 Heads . These heads were used on the 1986 to 1992 Z-28s and T/As with the 5.7 TPI engines . They are 64cc and have 1.94in/1.50ex valves . I can tell you this they are not light castings I will mark all the valves . Then re-move them and do some porting . Also I will install a set of GEN I Z-28/LT-1 Springs .

Speedy 55299, Thanks for the reassurance. My engine has been sitting unstarted for about two years but it was built for about $1800 until I wasted another $200 having the exhaust ports smoothed out. You can buy a rebuild kit for about $250 with flat top eybrow pistons, bore the block 0.030" and clean up the crank for about $200 in machining buy a Speedway cam, new lifters, Z28 springs and shave the heads (882) to a 70 cc chamber and pay for a three angle valve job and add a Performer intake with headers and you should be in the 280 HP range with a stock HEI distributor and whatever carb you have. A few years ago there was a similar rebuild on Street Rodder magazine that got 300 HP with a stock rebuild, Performer intake, three angle valve job, 882 heads and a longer duration cam. Prices may have gone up but the easy way to getting HP seems to be with a longer duration cam, but that may reduce the low rpm torque. All you need is one of thise rebuild kits with their longer duration cam and a Performer intake. I opted for a stock 300 HP cam with 1.6 rockers for low rpm torque. I hope to get it running as soon as the weather warms up.

Bought these Chrome Moly pushrods from a Camaro guy #RP-3212 R $25.00 bucks with the shipping . COOL

I pick up some more parts for the Budget 350 . The intake is a never used Professional products . It's a Dual plane- called a Cyclone # 52001 very much Like an Edelbrock # 2101 Performer . Also with this Deal . A Speed Pro Camshaft # CS1014R it's 204/214 dur at .050 and 420/443 Lift with a 112 C/L . Not a bad cam but I will save it for my pick up truck . The other parts are Speed Pro High-Rev Anti-pump-up Lifters a set of new 5/16" Chrome Moly Pushrods ( Just bought a set last week but can use them on another build ) . And a Cloyes HD Double Roller Timing set . Also with these parts a never open Fel-Pro 350 gasket set . All the parts are new. The guy just changed his mind on using them and sold his car . He was happy to get $150.00 Bucks for all this stuff ? So was Tango . COOL
