Contents of the Summit Top End Kit There are a number of kits that Summit offers for the small-block V-8, and after some advice from a Summit phone rep, we got the SME-K-355-400 kit with Trick Flow 62cc chamber aluminum heads and a Summit hydraulic flat tappet camshaft that is good for the 1,600- to 5,200-rpm range. The kit includes: Summit Racing hydraulic flat tappet camshaft, 272/282 duration, 0.442/0.465 lift Summit camshaft lock plate Summit hydraulic lifters, flat tappet Summit/Trick Flow loaded smog-legal aluminum heads, 62cc chamber, 170cc intake runner Summit True Roller timing set, double roller, steel sprockets Summit Stage 1 aluminum dual-plane intake manifold Summit intake manifold bolts Trick Flow full gasket set Trick Flow cylinder head bolts Trick Flow adjustable pushrod length checker 08. Unfortunately, things did not turn out exactly like we planned with the bottom end. When we bought the truck, we were told the engine didn’t have many miles since a rebuild and that the head gaskets had been blown. For $900, the truck was a great deal and it wasn’t a big problem since we planned on doing the Summit Top End kit right from the get go. When we cracked into the engine, we found a slightly different tale. It looks like the engine either had a lot more miles than stated or had been really pounded on when the head gaskets blew. We’re also not sure how long it had been sitting since the head gaskets had been blown—the license plate tags were last updated in 2010, so we assume at least two years. The surface rust and marks on the cylinder walls ensured this bottom end was not usable in its current state. 09. Before we got the heads off, we saw a good indicator that great care was not taken the last time this engine was rebuilt. The red paint overspray on the valves and valve springs say “rush job” to us. Instead of messing with our existing short-block, we decided to scrap it completely and look for a rebuilt four-bolt main short-block to start with. While the Top End kit we’re using may be inexpensive, that doesn’t mean we want to start with a junk bottom end. « | 1 | 2 | View Full Article By Jerrod Jones Enjoyed this Post?
