The camshaft and all valve gear components should be washed in solvent (with the exception of hydraulic lifters which will become contaminated) and dried thoroughly. Before installing your new camshaft, the part numbers of the camshaft and valve gear components should be checked to coincide with those in this catalog, to avoid any mismatch of equipment in the event of a shipping error. Your racing cam should also turn this freely in the block, when installed correctly. If you cannot find the timing marks, DO NOT remove the camshaft - consult a motor manual.Īfter removing the timing chain and lifters, place the cam sprocket back on the camshaft and revolve the cam in the block by hand and observe how freely it turns. Chevy however, procedures vary from engine to engine. *Shown is the procedure for aligning timing marks on a 427-cu-in. If these timing marks are not aligned properly during assembly, the camshaft will be out of phase with the crankshaft and the valves may be damaged if they strike the pistons. Be sure that when installing your new camshaft you align these timing marks in the same, position (see Fig. Probably anyone with some natural feel for mechanics can install a racing camshaft, especially if he is careful and observant, before and during the removal of the stock camshaft.īefore removing the stock camshaft, revolve the crankshaft slowly a few turns and notice the position of the timing marks on the cam and crank sprockets, with the No. 305 heads are worth rebuilding, even for a 350.A racing camshaft is a precision product that requires tender loving care in its installation. If it needs to go to a machine shop for anything more than tanking, just get a 350. My advice is to not spend a dime on a 305 shortblock beyond rings, bearings, and oil pump. If the engine was "blown" then you also need to replace any broken parts it is very possible that the block was damaged beyond repair. Keeping this in view, how much does it cost to rebuild a 350 small block?Ī re-build kit is $500, another $500 for machine shop work and then labor/time to rebuild it.
Likewise, how much does it cost to rebuild a Chevy 305? With the quotes so far for rebuilds of the 305, range anywhere from $1100 to $4000, from basic rebuild to upgrading pistons, rods, cam and so on. Generally, for a "good" rebuild that doesn't really get beyond 'mild 350' standards, you're looking at about $1,600-2,500 depending upon location.Īlso know, how much does it cost to rebuild a Chevy engine?Ī typical engine rebuild is between $2,500 and $4,000 in parts and labor costs. $600 to $3,500 depending upon how involved you want to get with the thing.
